CMake: Enable NEW policies by CMake version with a global default When a CMake release introduces a new policy that affects most Qt modules, it may be appropriate to make each module aware of that newer CMake version and use the NEW policy without raising the minimum CMake version requirement. To reduce the churn associated with making that change across all Qt modules individually, this change allows it to be updated in a central place (qtbase), but in a way that allows a Qt module to override it in its own .cmake.conf file if required (e.g. to address the issues identified by policy warnings at a later time). The policies are modified at the start of the call to qt_build_repo_begin(). For commands defined by the qtbase module, qtbase needs to be in control of the policy settings at the point where those commands are defined. The above mechanism should not affect the policy settings for these commands, so the various *Config.cmake.in files must not specify policy ranges in a way that a Qt module's .cmake.conf file could influence. Starting with CMake 3.12, policies can be specified as a version range with the cmake_minimum_required() and cmake_policy() commands. All policies introduced in CMake versions up to the upper limit of that range will be set to NEW. The actual version of CMake being used only has to be at least the lower limit of the specified version range. This change uses cmake_minimum_required() rather than cmake_policy() due to the latter not halting further processing upon failure.

Fix error when re-configuring an already installed Qt repository When building and installing a Qt repo that provides plugins for a Qt module within a different repository (for example, qtimageformats providing imageformat plugins for QtGui), re-configuring that repository would result in configuration errors like "add_library cannot create ALIAS target "Qt6::QTgaPlugin" because another target with the same name already exists." This happened, because the find_package(Qt6 COMPONENTS Gui) calls pulled in the Qt6*PluginConfig.cmake files that create imported targets for the plugins we want to build. To fix this, when building Qt, we now load only plugins that are provided by repositories the currently building repository depends on. We read the repo dependencies from dependencies.yaml when the Qt6BuildInternals package is loaded, but only in static builds and only if we're currently building a Qt repository. To find out whether we're building a Qt repository, we check whether QT_REPO_MODULE_VERSION is defined. We cannot check QT_BUILDING_QT, because that variable is not available for the first find_package calls in the repository's top-level project file. In each Qt6*PluginConfig.cmake file, we bail out if the plugin's repository is not one of the ones in QT_REPO_DEPENDENCIES.

CMake: Fix picking of the binary_for_strip project location Fix binary_for_strip project not being found when the following conditions were met: - building a repo other than qtbase - qtbase sources are not available on the machine (usually happens in CI where only the current repo sources are available). The issue was that QT_CMAKE_DIR would always be defined, regardless of which repo was being built and the system would incorrectly assume the location of the project files. The fix is to always pick up the sources from qtbase's source dir if they are available (this time done with an appropriate check), otherwise use the installed files. Note that the behavior of always using the qtbase sources if available is not exactly the best, but it is a more general issue that affects other code too. In the name of consistency, make it so for the binary_for_strip project as well, but add TODOs in code to address the situation in a separate change.

Use the qt_build_repo() macros for building qtbase as well To implement this, create a new Qt5BuildInternals package. All child Qt modules like qtsvg should use find_package(Qt5BuildInternals) or find_package(Qt5 COMPONENTS BuildInternals) in the their top level CMakeLists.txt. This will make the qt_build_repo() macros available. For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH pointing to the source folder that contains the BuildInternals package. For the other modules we actually use a configured and installed package Config file. This change moves variables that used to be written into the QtCore Config file into the BuildInternals package. This way things that are relevant only for building additional Qt modules does not pollute the QtCore package.

CMake: Provide script to configure and build one or more tests Before this patch there were a few ways to build tests - Configure all tests as part of the repo build - Configure all tests as part of the repo build, but don't build tests by default (-DQT_NO_MAKE_TESTS=ON) - Configure all tests as a standalone project in a separate build dir using -QT_BUILD_STANDALONE_TESTS=ON All of the above incur some time overhead due to the necessity of configuring all tests. Sometimes you just want to build ONE test (or a few). To facilitate that use case, a new shell script called bin/qt-cmake-standalone-test(.bat) can now be used to configure and build one or more tests. The script takes one single argument pointing to the desired test project path and configures a generic template project that sets up all the necessary Qt CMake private API, afterwards calling add_subdirectory on the passed in project. Example $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image/qicon or $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image After that, simply run 'ninja && ctest' to build and run the test(s). This is the CMake equivalent of calling qmake on a test .pro file (or on a tests SUBDIRS .pro file) There are 3 details worth mentioning. Due to the add_subdirectory call, the built artifacts will not be in the top-level build dir, but rather in a nested build_dir. The script currently can't handle more than one argument (the path to the project), so you can't pass additional -DFoo=bar arguments. If a test uses a 3rd party library (like Threads::Threads) which was not a public dependency for any of the Qt modules, configuration will fail saying that the target was not found. Perhaps we should consider recording these packages when generating the StandaloneConfig.cmake files.

CMake: Bump the minimum required CMake version to build Qt to 3.18 Add a new function that returns the minimum CMake version required to build Qt. Pass that value to cmake_minimum_required() when building qtbase and its standalone tests. The minimum supported CMake version is read from qtbase/.cmake.conf and its value should be updated when the need arises. It's the main source of truth for all repos. Provide a way to lower the minimum CMake version at configure time by passing a value via QT_FORCE_MIN_CMAKE_VERSION. This is not an officially supported way of building Qt. If the specified version is lower than Qt's supported minimum, show a warning. Nevertheless the option is useful for testing how Qt builds with a different minimum CMake version due to different policies being enabled by default. Issue warnings for CMake versions that are higher than the minimum version but are known to cause issues when building Qt. A counterpart change is needed in qt5 to ensure the minimum CMake version is set at the proper time for top-level builds. Ideally we would use the same 'check the CMake minimum version` code in all our repositories, but that will cause lots of duplication because we can't really find_package() the code and doing something like include(../qtbase/foo.cmake) hardcodes assumptions about repo locations. So for now we don't bump the minimum version in child repo cmake_minimum_required calls (qtsvg, qtdeclarative, etc). Instead we record both the minimum supported version and the computed minimum version (in case a different version was forced) in QtBuildInternalsExtra.cmake. Then we require qtbase's computed min version in qt_build_repo_begin(). This won't set policies as cmake_minimum_required would, but at least it propagates what minimum CMake version should be used for child repos. We might still have to bump the versions in child repos at some point.

CMake: Enable NEW policies by CMake version with a global default When a CMake release introduces a new policy that affects most Qt modules, it may be appropriate to make each module aware of that newer CMake version and use the NEW policy without raising the minimum CMake version requirement. To reduce the churn associated with making that change across all Qt modules individually, this change allows it to be updated in a central place (qtbase), but in a way that allows a Qt module to override it in its own .cmake.conf file if required (e.g. to address the issues identified by policy warnings at a later time). The policies are modified at the start of the call to qt_build_repo_begin(). For commands defined by the qtbase module, qtbase needs to be in control of the policy settings at the point where those commands are defined. The above mechanism should not affect the policy settings for these commands, so the various *Config.cmake.in files must not specify policy ranges in a way that a Qt module's .cmake.conf file could influence. Starting with CMake 3.12, policies can be specified as a version range with the cmake_minimum_required() and cmake_policy() commands. All policies introduced in CMake versions up to the upper limit of that range will be set to NEW. The actual version of CMake being used only has to be at least the lower limit of the specified version range. This change uses cmake_minimum_required() rather than cmake_policy() due to the latter not halting further processing upon failure.

Use the qt_build_repo() macros for building qtbase as well To implement this, create a new Qt5BuildInternals package. All child Qt modules like qtsvg should use find_package(Qt5BuildInternals) or find_package(Qt5 COMPONENTS BuildInternals) in the their top level CMakeLists.txt. This will make the qt_build_repo() macros available. For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH pointing to the source folder that contains the BuildInternals package. For the other modules we actually use a configured and installed package Config file. This change moves variables that used to be written into the QtCore Config file into the BuildInternals package. This way things that are relevant only for building additional Qt modules does not pollute the QtCore package.

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

CMake: Adjust compiler flag optimizations to qmake mkspec ones There are inconsistencies in the default optimization flags added by CMake across configurations like Release and RelWithDebInfo. In particular Release uses -O3, whereas RelWithDebInfo uses -O2, as well as usage of /INCREMENTAL in release configs with MSVC, etc. To make sure that the Qt 6 binaries built with CMake are consistent across configs, as well as consistent with the flags we used when building Qt 5 with qmake, add a horrible search and replace mechanism to replaces the CMake flags with what our mkspecs indicate to use. Ideally this would be done by providing custom CMake toolchain files for each platform we support, and we might revisit that later if the need really arises. To implement the replacing, we first need the flags that should be added. Port the QMAKE_CFLAGS_OPTIMIZE variables to CMake, which is done in QtCompilerOptimization.cmake. Then a new function called qt_internal_set_up_config_optimizations_like_in_qmake will look for any kind of optimization flags set in the CMAKE_<LANG>_FLAGS_<CONFIG> style variables, remove them, and add the appropriate flags that qmake mkspecs provide. On some platforms (like Windows MSVC) the function also alters the linker CMAKE_${TYPE}_LINKER_FLAGS_<CONFIG> style variables. The mechanism allows opting out of this replacing by setting the QT_USE_DEFAULT_CMAKE_OPTIMIZATION_FLAGS value. It also allows opting into removal of flags for custom configs by providing QT_ADDITIONAL_OPTIMIZATION_FLAG_CONFIGS. It's only removal, because we wouldn't know what kind of config it is, and thus what flags to add. The currently modified configs are: Release, RelWithDebInfo, MinSizeRel, Debug aka the usual default CMake provided ones. The mechanism is only applied to C-like languages. ASM is not handled to be on the safe side due to not knowing what kind of compiler flags the platform assembler might take. It's also important to skip RC on MSVC platforms.

CMake: Refactor optimization flag handling and add optimize_full Introduce a bunch of helper functions to manipulate compiler flags and linker flags for the CMAKE_<LANG>_FLAGS_<CONFIG> and CMAKE_<LINK_TYPE>_LINKER_FLAGS_<CONFIG> CMake variables. These variables can be assigned and modified either in the cache or for a specific subdirectory scope, which will apply the flags only to targets in that scope. Add qt_internal_add_optimize_full_flags() function which mimics qmake's CONFIG += optimize_full behavior. Calling it will force usage of the '-O3' optimization flag on supported platforms (falling back '-O2' where not supported). Use the function for the Core and Gui subdirectories, to enable full optimization for the respective Qt modules as it is done in the qmake projects. To ensure that the global qmake-like compiler flags are assigned eveywhere, qt_internal_set_up_config_optimizations_like_in_qmake() needs to be called after Qt global features like optimize_size and optimize_full are available. This means that qtbase and its standalone tests need some special handling in regards to when to call that function.

CMake: Provide script to configure and build one or more tests Before this patch there were a few ways to build tests - Configure all tests as part of the repo build - Configure all tests as part of the repo build, but don't build tests by default (-DQT_NO_MAKE_TESTS=ON) - Configure all tests as a standalone project in a separate build dir using -QT_BUILD_STANDALONE_TESTS=ON All of the above incur some time overhead due to the necessity of configuring all tests. Sometimes you just want to build ONE test (or a few). To facilitate that use case, a new shell script called bin/qt-cmake-standalone-test(.bat) can now be used to configure and build one or more tests. The script takes one single argument pointing to the desired test project path and configures a generic template project that sets up all the necessary Qt CMake private API, afterwards calling add_subdirectory on the passed in project. Example $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image/qicon or $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image After that, simply run 'ninja && ctest' to build and run the test(s). This is the CMake equivalent of calling qmake on a test .pro file (or on a tests SUBDIRS .pro file) There are 3 details worth mentioning. Due to the add_subdirectory call, the built artifacts will not be in the top-level build dir, but rather in a nested build_dir. The script currently can't handle more than one argument (the path to the project), so you can't pass additional -DFoo=bar arguments. If a test uses a 3rd party library (like Threads::Threads) which was not a public dependency for any of the Qt modules, configuration will fail saying that the target was not found. Perhaps we should consider recording these packages when generating the StandaloneConfig.cmake files.

Rework how installation is prevented in non-prefix builds In non-prefix builds, we want to prevent users from accidentally running "cmake --install". We did that by replacing cmake_install.cmake with an empty file. The responsible target remove_cmake_install is visible in IDEs, appears in the build output, and the approach is hacky. It's cleaner and easier to add bail out code at the top of cmake_install.cmake. This is now done when calling qt_build_repo_begin. As a bonus, print an informative message on installation.

CMake: Adjust PCH support for multi-arch iOS builds Starting with CMake 3.18, there is PCH support for darwin multi-arch builds, like iOS simulator_and_device builds. Also enable PCH for Objective-C++ files when the support is there. To enable PCH for Objective-C++, we need to do enable the OBJCXX language as well, but conditionally, because on non-darwin platforms the language is probably not available. Introduce the qt_enable_cmake_languages() macro which is called automatically by qt_build_repo_begin().

CMake: Generate and use a wrapper script for stripping binaries MinGW 11.2.0 comes with a strip.exe that strips the ".gnu_debuglink" section in binaries, a section that is needed for the separate debug information feature. binutils version 2.34 mentions the feature for the first time: https://sourceware.org/binutils/docs-2.34/binutils/strip.html#strip To ensure the debuglink section is preserved, generate a shell wrapper that calls the original strip binary with an extra option to keep the required section. To determine if the option is supported, we build a real shared library on which strip will be called with the --keep-section option. If the option is not supported, a wrapper is not generated and the stock strip binary is used. This logic only applies when targeting Linux and MinGW + a shared library Qt. For other targets, the stock strip binary is used. Developers can opt out of this logic by passing -DQT_NO_STRIP_WRAPPER=TRUE when configuring each Qt repo.

Replace the syncqt.pl script with syncqt tool syncqt.pl adds an extra dependency on perl when building Qt. Modern C++ provides the convenient cross-platform way to access a filesystem and to use regular expressions, so we may replace the perl script with C++ application. The syncqt executable is built at configure time and installed as QtCore tool. It's running at configure time to deliver the required header files for IDE to build a consistent code model and at the build time to keep tracking changes in header files and generate the missing aliases without reconfiguring. 'syncqt' only parses header files from a CMake build tree, so the resulting Qt installation only contains interfacing headers that belong to the platform that Qt is built for. 'sync.profile' files are not used as the 'source of truth' for sync qt procedure anymore, all the necessary information is taken from either CMake files at configure time or from the module header files while parsing them. syncqt.pl is still in place since it's required as fallback solution for a smooth transition to the new syncqt implementation for all qt repositories. This patchset only enables the C++ based syncqt for 'qtbase' repository. From the performance perspective C++ version works faster then perl script, also the configure time is reduced significally on subsequent reconfigurations - up x2 times faster when re-configuring repository, but it also takes time to compile the tool itself the first time. Numbers for qtbase: syncqt.pl syncqt.cpp initial: 0m16,035s 0m20,413s reconfig: 0m6,819s 0m3,725s The syncing procedure can be run separately for each module using <ModuleName>_sync_headers targets.

# Make top-level prepare_docs target depend on the repository-level prepare_docs_<repo> target.
CMake: Add global / top-level docs targets Previously you could use either module-specific or repo-specific 'docs' targets. For example 'ninja html_docs_qtbase' or 'ninja html_docs_Core'. Now there's a global / top-level target called 'docs', so 'ninja docs' works. For super builds it will build the documentation of all configured repositories. For a single repo build, it's equivalent to calling 'ninja docs_repo_name'. Also for consistency, add the "docs_Core" target, which was missing before. So now a 'docs' target exsits for repo names AND targets. New global target names are - docs - prepare_docs - generate_docs - html_docs - qch_docs - install_html_docs_docs - install_qch_docs_docs - install_docs_docs Amends 0095ff4e0659906595d281b37c3b7f89e37250af Change-Id: I686be1e0962e40cbce860e8ac2cabb056b360ac2 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

Replace the syncqt.pl script with syncqt tool syncqt.pl adds an extra dependency on perl when building Qt. Modern C++ provides the convenient cross-platform way to access a filesystem and to use regular expressions, so we may replace the perl script with C++ application. The syncqt executable is built at configure time and installed as QtCore tool. It's running at configure time to deliver the required header files for IDE to build a consistent code model and at the build time to keep tracking changes in header files and generate the missing aliases without reconfiguring. 'syncqt' only parses header files from a CMake build tree, so the resulting Qt installation only contains interfacing headers that belong to the platform that Qt is built for. 'sync.profile' files are not used as the 'source of truth' for sync qt procedure anymore, all the necessary information is taken from either CMake files at configure time or from the module header files while parsing them. syncqt.pl is still in place since it's required as fallback solution for a smooth transition to the new syncqt implementation for all qt repositories. This patchset only enables the C++ based syncqt for 'qtbase' repository. From the performance perspective C++ version works faster then perl script, also the configure time is reduced significally on subsequent reconfigurations - up x2 times faster when re-configuring repository, but it also takes time to compile the tool itself the first time. Numbers for qtbase: syncqt.pl syncqt.cpp initial: 0m16,035s 0m20,413s reconfig: 0m6,819s 0m3,725s The syncing procedure can be run separately for each module using <ModuleName>_sync_headers targets.

Use the qt_build_repo() macros for building qtbase as well To implement this, create a new Qt5BuildInternals package. All child Qt modules like qtsvg should use find_package(Qt5BuildInternals) or find_package(Qt5 COMPONENTS BuildInternals) in the their top level CMakeLists.txt. This will make the qt_build_repo() macros available. For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH pointing to the source folder that contains the BuildInternals package. For the other modules we actually use a configured and installed package Config file. This change moves variables that used to be written into the QtCore Config file into the BuildInternals package. This way things that are relevant only for building additional Qt modules does not pollute the QtCore package.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

CMake: Reconfigure faster by not looking for missing packages Instead of constantly trying to find packages by calling qt_find_package on each reconfiguration, record which packages were found during initial configuration.

With this change, they will first have to remove their CMakeCache.txt file and configure from scratch, or remove the QT_INTERNAL_PREVIOUSLY_FOUND_PACKAGES cache variable and reconfigure. For this reason, we enable this behavior by default only in -developer-builds. Builders can also opt in or out by setting the QT_INTERNAL_SAVE_PREVIOUSLY_FOUND_PACKAGES variable to either ON or OFF. Note this behavior does not apply to user projects, or direct find_package calls (as opposed to qt_find_package).

CMake: Record used package version for each target dependency When recording which package version to look for in QtFooModuleDependencies.cmake and other files like it, instead of using PROJECT_VERSION, use the version of the package that contains the dependency. For example if we're hypothetically building the qtdeclarative repo from the 6.4 branch, against an installed 6.2 qtbase, then the Qt6QmlModuleDependencies.cmake file will have a find_package(Qt6Core 6.2) call because qtdeclarative's find_package(Qt6Core) call found a 6.2 Core when it was configured. This allows switching the versioning scheme of specific Qt modules that might not want to follow the general Qt versioning scheme. The first candidate would be QtWebEngine which might want to follow the Chromium versioning scheme, something like Qt 6.94.0 where 94 is the Chromium major version. Implementation notes. We now record the package version of a target in a property called _qt_package_version. We do it for qt modules, plugins, 3rd party libraries, tools and the Platform target. When we try to look up which version to write into the QtFooModuleDependencies.cmake file (or the equivalent Plugins and Tools file), we try to find the version from a few sources: the property mentioned above, then the Qt6{target}_VERSION variable, and finally PROJECT_VERSION. In the latter case, we issue a warning because technically that should never have to happen, and it's a bug or an unforeseen case if it does. A few more places also need adjustments: - package versions to look for when configuring standalone tests and generating standalone tests Config files - handling of tools packages - The main Qt6 package lookup in each Dependencies.cmake files Note that there are some requirements and consequences in case a module wants to use a different versioning scheme like 6.94.0. Requirements. - The root CMakeLists.txt file needs to call find_package with a version different from the usual PROJECT_VERSION. Ideally it should look for a few different Qt versions which are known to be compatible, for example the last stable and LTS versions, or just the lowest supported Qt version, e.g. 6.2.6 or whenever this change would land in the 6.2 branch. - If the repository has multiple modules, some of which need to follow the Qt versioning scheme and some not, project(VERSION x.y.z) calls need to be carefully placed in subdirectory scopes with appropriate version numbers, so that qt_internal_add_module / _tool / _plugin pick up the correct version. Consequences. - The .so / .dylib names will contain the new version, e.g. .so.6.94 - Linux ELF symbols will contain the new versions - syncqt private headers will now exist under a include/QtFoo/6.94.0/QtFoo/private folder - pri and prl files will also contain the new version numbers - pkg-config .pc files contain the new version numbers - It won't be possible to write find_package(Qt6 6.94 COMPONENTS WebEngineWidgets) in user code. One would have to write find_package(Qt6WebEngineWidgets 6.94) otherwise CMake will try to look for Qt6Config 6.94 which won't exist. - Similarly, a find_package(Qt6 6.4 COMPONENTS Widgets WebEngineWidgets) call would always find any kind of WebEngine package that is higher than 6.4, which might be 6.94, 6.95, etc. - In the future, if we fix Qt6Config to pass EXACT to its subcomponent find_package calls, a find_package(Qt6 6.5.0 EXACT COMPONENTS Widgets WebEngineWidgets) would fail to find WebEngineWidgets, because its 6.94.0 version will not be equal to 6.5.0. Currently we don't pass through EXACT, so it's not an issue.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

macro(qt_set_up_standalone_tests_build)
Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

CMake: Provide script to configure and build one or more tests Before this patch there were a few ways to build tests - Configure all tests as part of the repo build - Configure all tests as part of the repo build, but don't build tests by default (-DQT_NO_MAKE_TESTS=ON) - Configure all tests as a standalone project in a separate build dir using -QT_BUILD_STANDALONE_TESTS=ON All of the above incur some time overhead due to the necessity of configuring all tests. Sometimes you just want to build ONE test (or a few). To facilitate that use case, a new shell script called bin/qt-cmake-standalone-test(.bat) can now be used to configure and build one or more tests. The script takes one single argument pointing to the desired test project path and configures a generic template project that sets up all the necessary Qt CMake private API, afterwards calling add_subdirectory on the passed in project. Example $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image/qicon or $ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image After that, simply run 'ninja && ctest' to build and run the test(s). This is the CMake equivalent of calling qmake on a test .pro file (or on a tests SUBDIRS .pro file) There are 3 details worth mentioning. Due to the add_subdirectory call, the built artifacts will not be in the top-level build dir, but rather in a nested build_dir. The script currently can't handle more than one argument (the path to the project), so you can't pass additional -DFoo=bar arguments. If a test uses a 3rd party library (like Threads::Threads) which was not a public dependency for any of the Qt modules, configuration will fail saying that the target was not found.

# Of course we always need the test module as well.
CMake: Record used package version for each target dependency When recording which package version to look for in QtFooModuleDependencies.cmake and other files like it, instead of using PROJECT_VERSION, use the version of the package that contains the dependency. For example if we're hypothetically building the qtdeclarative repo from the 6.4 branch, against an installed 6.2 qtbase, then the Qt6QmlModuleDependencies.cmake file will have a find_package(Qt6Core 6.2) call because qtdeclarative's find_package(Qt6Core) call found a 6.2 Core when it was configured. This allows switching the versioning scheme of specific Qt modules that might not want to follow the general Qt versioning scheme. The first candidate would be QtWebEngine which might want to follow the Chromium versioning scheme, something like Qt 6.94.0 where 94 is the Chromium major version. Implementation notes. We now record the package version of a target in a property called _qt_package_version. We do it for qt modules, plugins, 3rd party libraries, tools and the Platform target. When we try to look up which version to write into the QtFooModuleDependencies.cmake file (or the equivalent Plugins and Tools file), we try to find the version from a few sources: the property mentioned above, then the Qt6{target}_VERSION variable, and finally PROJECT_VERSION. In the latter case, we issue a warning because technically that should never have to happen, and it's a bug or an unforeseen case if it does. A few more places also need adjustments: - package versions to look for when configuring standalone tests and generating standalone tests Config files - handling of tools packages - The main Qt6 package lookup in each Dependencies.cmake files Note that there are some requirements and consequences in case a module wants to use a different versioning scheme like 6.94.0. Requirements. - The root CMakeLists.txt file needs to call find_package with a version different from the usual PROJECT_VERSION. Ideally it should look for a few different Qt versions which are known to be compatible, for example the last stable and LTS versions, or just the lowest supported Qt version, e.g. 6.2.6 or whenever this change would land in the 6.2 branch. - If the repository has multiple modules, some of which need to follow the Qt versioning scheme and some not, project(VERSION x.y.z) calls need to be carefully placed in subdirectory scopes with appropriate version numbers, so that qt_internal_add_module / _tool / _plugin pick up the correct version. Consequences. - The .so / .dylib names will contain the new version, e.g. .so.6.94 - Linux ELF symbols will contain the new versions - syncqt private headers will now exist under a include/QtFoo/6.94.0/QtFoo/private folder - pri and prl files will also contain the new version numbers - pkg-config .pc files contain the new version numbers - It won't be possible to write find_package(Qt6 6.94 COMPONENTS WebEngineWidgets) in user code. One would have to write find_package(Qt6WebEngineWidgets 6.94) otherwise CMake will try to look for Qt6Config 6.94 which won't exist. - Similarly, a find_package(Qt6 6.4 COMPONENTS Widgets WebEngineWidgets) call would always find any kind of WebEngine package that is higher than 6.4, which might be 6.94, 6.95, etc. - In the future, if we fix Qt6Config to pass EXACT to its subcomponent find_package calls, a find_package(Qt6 6.5.0 EXACT COMPONENTS Widgets WebEngineWidgets) would fail to find WebEngineWidgets, because its 6.94.0 version will not be equal to 6.5.0. Currently we don't pass through EXACT, so it's not an issue.

The gist of it is that we have to protect tests not to be installed into the Qt install prefix, but we also have to make sure that the CMAKE_INSTALL_PREFIX is not changed globally (via cache value), so that reconfiguration still works. This took way too long to figure out.

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

Rename and restructure the baseline (lancelot) testing code In preparation for addition of new baseline tests, establish a new test category, "baseline". This is similar to the category "benchmarks" in that it contains tests that use the QTest framework, but conceptually are not unit tests, in contrast to those under auto/. Move the existing QPainter baseline test, tst_lancelot, into this new category, and rename it accordingly. Baseline tests use the QBaselineTest extension to QTest.

CMake: Make build system of installed Qt more relocatable Aka handle CMAKE_INSTALL_PREFIX in a more relocatable way. The following story inspired this change. If a user wants to build a Qt repo into a different install prefix than the usual Qt one, this will fail configuration because we look for various things like syncqt, qdoc, etc relative to CMAKE_INSTALL_PREFIX, which will now point to a different location where none of the above tools are located. The intent for such a use case is to support building Qt packages with Conan, which sets a random install prefix when configuring a repo. The idea is to derive the qt prefix dynamically from the QtBuildInternals package location. Essentially it's a reverse relative path from the QtBuildInternalsConfig.cmake file to the install prefix that was specified when initially configuring qtbase. Once the dynamic prefix is computed (so we know where the possibly relocated Qt is), we can find tools like syncqt and qdoc. This is an initial attempt to support a use case like that. More design work will probably needed in case if tools / libs need to be found in a location different than the Qt install prefix (so support for multiple install prefixes / search paths). An example of such a case would be when building qtdeclarative and qtquickcontrols2 as Conan packages in one go. Most likely the qmltyperegistrar tool will be located in the random install prefix set by Conan, so building qtquickcontrols2 might fail due to not finding the tool in the original Qt install prefix. As to the implementation details, the change does the following: - Dynamically computes and sets the QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable when find_package()'ing QtBuildInternals. It's an absolute path pointing to where the relocated Qt is. - When building qtbase this variable is not yet available (due to QtBuildInternalsExtra not existing), in that case we set the variable to the absolute path of CMAKE_INSTALL_PREFIX (but only for the initial qtbase configuration). - Remove QT_BUILD_INTERNALS_ORIGINAL_INSTALL_PREFIX which was used for standalone tests purposes. It's not needed now that we compute the location of the Qt prefix dynamically. - The Unixy qt-cmake and qt-cmake-private shell scripts now use a relative path to find the toolchain file we created. - The toolchain file also dynamically computes the location of the Qt packages, and adds them to CMAKE_PREFIX_PATH. - A lot of existing CMAKE_INSTALL_PREFIX uses are replaced with QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX. This includes finding tool locations, mkspecs dir, path environment setup for tools, etc. - Some places still use CMAKE_PREFIX_PATH in the following cases - When determining paths while configuring qtbase (valid cases) - When I wasn't sure what the behavior should be, so I left them as-is (an example is documentation generation, do we want to install it into the random Conan prefix, or into the main prefix? Currently it installs in the random prefix).

This includes finding tool locations, mkspecs dir, path environment setup for tools, etc. - Some places still use CMAKE_PREFIX_PATH in the following cases - When determining paths while configuring qtbase (valid cases) - When I wasn't sure what the behavior should be, so I left them as-is (an example is documentation generation, do we want to install it into the random Conan prefix, or into the main prefix? Currently it installs in the random prefix). Note that relocating a Qt installation does not work for non-prefix / non-installed builds, due to hardcoded paths to include directories and libraries in generated FooTargets.cmake files.

CMake: Deduce install prefix of example in qt_internal_add_example We want to get rid of the INSTALL_EXAMPLEDIR and INSTALL_EXAMPLESDIR code in each example project. This was an internal workaround to ensure examples are installed into a relative path somewhere under $qt_prefix/examples and not in $qt_prefix/bin or similar. To achieve that we do two things. First, deduce the install prefix for each example in the implementation of qt_internal_add_example (our add_subdirectory wrapper) and assign it to CMAKE_INSTALL_PREFIX before calling add_subdirectory. We need to make sure to remove the default value of CMAKE_INSTALL_PREFIX in the generated cmake_install.cmake file. Second, we set an internal variable called QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT before the add_subdirectory call, which will be checked whenever find_package(Qt6Core) is called in an example project. If the variable is set, the INSTALL_EXAMPLEDIR var is set to "." in the scope of where Qt6Core is found. This ensures that the hardcoded INSTALL_EXAMPLEDIR values in our example projects are changed to ".". With both changes, our example project install(TARGET DESTINATION) calls will now install to "${CMAKE_INSTALL_PREFIX}/examples/${example_relative_dir}/." Once all repositories are updated to use qt_internal_add_example instead of add_subdirectory, we can get rid of the QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT workaround. For repositories that still don't use qt_internal_add_example, the install prefix rewriting will not happen, but the examples will still be installed to the proper place because they use their own hardcoded INSTALL_EXAMPLEDIR value.

CMake: Allow opting out of building examples as ExternalProjects We default to configuring examples as separate ExternalProjects when using a developer / non-prefix Qt build. This ensures we test that the examples configure successfully without the pollution of the main Qt build (e.g. already found packages). One down-side of this is that a developer's IDE doesn't see these example targets, unless each project is loaded into the IDE separately. This is cumbersome to do when refactoring or renaming code across multiple example projects. Allow configuring the example projects as part of the main Qt build by setting QT_BUILD_EXAMPLES_AS_EXTERNAL to FALSE when configuring Qt.

This leads to the following error when trying to build qttools together with examples as ExternalProjects and Ninja Multi-Config: ninja: error: 'src/designer/src/designer/designer_autogen/ include_Debug/ui_preferencesdialog.h', needed by 'src/designer/src/designer/designer_autogen:Debug', missing and no known rule to make it Until cmake is fixed, we can work around the issue by not adding designer as a dependency when building EP examples, because no example tries to use the app. We can't exclude all apps from example dependencies because some modules use qt_internal_add_app for tools as well, which are called from public CMake API and also examples. An example of this is qtapplicationmanager. Given that we can't exclude all apps, introduce a function to allow skipping single targets when building EP examples. This will allow excluding designer specifically. The examples will now depend on a new ${repo}_src_for_examples target rather than ${repo}_src, which will exclude skipped targets.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

CMake: Handle automatic rpath embedding correctly Instead of using CMAKE_INSTALL_RPATH to embed an absolute path to prefix/libdir into all targets, use the more sophisticated aproach that qmake does. For certain targets (modules, plugins, tools) use relative rpaths. Otherwise embed absolute paths (examples, regular binaries). Installed tests currently have no rpaths. On certain platforms rpaths are not used (Windows, Android, iOS / uikit). Frameworks, app bundles and shallow bundles should also be handled correctly. Additional rpaths can be provided via QT_EXTRA_RPATHS variable (similar to the -R option that configure takes). Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF or QT_DISABLE_RPATH=ON. Note that installed examples are not relocatable at the moment (due to always having an absolute path rpath), so this is a missing feature compared to qmake. This is due to missing information on where examples will be installed, so a relative rpath can not be computed. By default a Qt installation is relocatable, so there is no need to pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R . Relative rpaths will have the appropriate 'relative base' prefixed to them (e.g $ORIGIN on linux and @loader_path on darwin platforms). There is currently no support for other platforms that might have a different 'relative base' than the ones mentioned above. Any extra rpaths are saved to BuildInternalsExtra which are re-used when building other repositories. configurejson2cmake modified to include correct conditions for the rpath feature. It's very likely that we will need a new qt_add_internal_app() function for gui apps that are to be installed to prefix/bin. For example for Assistant from qttools. Currently such apps use qt_add_executable(). The distinction is necessary to make sure that relative rpaths are embedded into apps, but not executables (which tests are part of).

CMake: Deduce install prefix of example in qt_internal_add_example We want to get rid of the INSTALL_EXAMPLEDIR and INSTALL_EXAMPLESDIR code in each example project. This was an internal workaround to ensure examples are installed into a relative path somewhere under $qt_prefix/examples and not in $qt_prefix/bin or similar. To achieve that we do two things. First, deduce the install prefix for each example in the implementation of qt_internal_add_example (our add_subdirectory wrapper) and assign it to CMAKE_INSTALL_PREFIX before calling add_subdirectory. We need to make sure to remove the default value of CMAKE_INSTALL_PREFIX in the generated cmake_install.cmake file. Second, we set an internal variable called QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT before the add_subdirectory call, which will be checked whenever find_package(Qt6Core) is called in an example project. If the variable is set, the INSTALL_EXAMPLEDIR var is set to "." in the scope of where Qt6Core is found. This ensures that the hardcoded INSTALL_EXAMPLEDIR values in our example projects are changed to ".". With both changes, our example project install(TARGET DESTINATION) calls will now install to "${CMAKE_INSTALL_PREFIX}/examples/${example_relative_dir}/." Once all repositories are updated to use qt_internal_add_example instead of add_subdirectory, we can get rid of the QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT workaround. For repositories that still don't use qt_internal_add_example, the install prefix rewriting will not happen, but the examples will still be installed to the proper place because they use their own hardcoded INSTALL_EXAMPLEDIR value.

If the variable is set, the INSTALL_EXAMPLEDIR var is set to "." in the scope of where Qt6Core is found. This ensures that the hardcoded INSTALL_EXAMPLEDIR values in our example projects are changed to ".". With both changes, our example project install(TARGET DESTINATION) calls will now install to "${CMAKE_INSTALL_PREFIX}/examples/${example_relative_dir}/." Once all repositories are updated to use qt_internal_add_example instead of add_subdirectory, we can get rid of the QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT workaround. For repositories that still don't use qt_internal_add_example, the install prefix rewriting will not happen, but the examples will still be installed to the proper place because they use their own hardcoded INSTALL_EXAMPLEDIR value.

Fix Standalone Example build when crosscompiling Added qt_examples_begin() and qt_examples_end() macros to setup the example list so it can be re-used in other projects. When cross-compiling, we also need to set CMAKE_FIND_ROOT_PATH_MODE_PACKAGE to BOTH in order for find_package() to work correctly. Removed support for building the whole qtbase/examples folder as a standalone project. Building examples is only supported when building the whole of qtbase (qtbase + examples together) or each individual example is built separately against an installed Qt version.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time.

CMake: Allow specifying custom install dir for non-EP examples Originally, QT_INTERNAL_EXAMPLES_INSTALL_PREFIX was added to control the installation of examples when they are built as ExternalProjects, and was not considered for the non-EP case because we hoped to switch entirely to EP-based building. Due to some unsolved issues regarding using EP builds in CI, add the ability to control the installation of non-EP examples. This will be used in the CI to allow removing the hacky INSTALL_EXAMPLEDIR and INSTALL_EXAMPLESDIR assignments in example projects. It is also likely that we will not deprecate the non-EP based building, because it is useful for IDE integration (EP targets are not as developer-friendly to work with in an IDE in regards to rebuilding).

CMake: Build examples as ExternalProjects in prefix builds Change prefix builds to use ExternalProjects to build examples by default. This will affect our CI which only does prefix builds. To make it work, we have to do a few adjustments: - look for Config files in the build-tree (before Qt is installed) - build only one examples with only a single config, even if Qt is a multi-config build - install examples as part of main make install step, rather than as part of the make step (which is the default for EPs) - adjust CXX flags when building with MSVC to ensure we can still use sccache and separate debug info - derive the correct install prefix for each example and pass it to the ExternalProject As a drive-by, add TODOs to address tidiness of the code and corner cases that likely don't work (Conan).

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

Build examples in isolated sub-builds using ExternalProject Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

function(qt_internal_static_link_order_test)
Check the impact of static link order for user projects For user projects we run the static link order check once 'find_package(Qt6 ...)' is called. If linker can resolve circular dependencies between static libraries and object files we set the _qt_link_order_matters property of the Qt::Platform target. This indicates the use of finalizers is not required and we may rely on CMake-base propagation of resource libraries and resource object files. If linker could not resolve circular dependencies depending on the _qt_resource_objects_finalizer_mode value: - Finalizer will be called and collected resource objects will be linked to the target directly. - Finalizer will be omitted and resource objects will be linked using the target_sources function implicitly. This only propagates resource one level up if consumer links the static library PUBLICly, but all symbols will be resolved correctly since object files are placed in the beginning of the linker line. In the CMake version 3.21 we expect that CMake will take care about the order of the resource object files in a linker line, it's expected that all object files are located at the beginning of the linker line.

Use target_link_options to propagate object libraries target_link_options are placed by CMake at the beginning of a linker line. This gives us an opportunity to use the function to propagate object libraries. This change adds one more check in the root Config.cmake file. If CMP0099 policy is enabled, CMake enables propagating of the linking options when linking two static libraries using the PRIVATE linking visibility, so we can rely on the correct linking order and expect object libraries to be propagated. Note that on the platforms where cmake version is higher than 3.16 Qt uses CMP0099 NEW in functions like qt_add_executable. This means that at the moment of creating an executable target the TARGET_POLICY genex will also be NEW, so we do not take into the account the user defined CMP0099. If the CMP0099 policy is not available for a certain CMake version we skip the TARGET_POLICY check and simply disable propagation of the object libraries using target_link_options for both user and Qt libraries. This is applicable for the CMake versions 3.16 and less. Linking approaches have the following priorities(from higher to lower) after this change: - target_link_libraries - works if link order matters not or CMake version greater equal 3.21. - target_link_options - works if CMP0099 is set to NEW by user or if the CMake version is greater than or equal to 3.17 and an executable is created using Qt functions. - object library finalizer - works if CMake version is greater equal 3.19 or qt6_finalize_target is called explicitly. - target_sources - is used when all the other approaches could not be used.
