Implement developer / non-prefix builds A non-prefix build is a build where you don't have to run make install. To do a non-prefix build, pass -DFEATURE_developer_build=ON when invoking CMake on qtbase. Note that this of course also enables developer build features (private tests, etc). When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable will point to the qtbase build directory. Tests can be run without installing Qt (QPA plugins are picked up from the build dir). This patch stops installation of any files by forcing the make "install" target be a no-op. When invoking cmake on the qtsvg module (or any other module), the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build directory. The developer-build feature is propagated via the QtCore Config file, so that when building other modules, you don't have to specify it on the command line again. As a result of the change, all libraries, plugins, tools, include dirs, CMake Config files, CMake Targets files, Macro files, etc, will be placed in the qtbase build directory, mimicking the file layout of an installed Qt file layout. Only examples and tests are kept in the separate module build directories, which is equivalent to how qmake does it. The following global variables contain paths for the appropriate prefix or non prefix builds: QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR, QT_CONFIG_INSTALL_DIR. These should be used by developers when deciding where files should be placed. All usages of install() are replaced by qt_install(), which has some additional logic on how to handle associationg of CMake targets to export names. When installing files, some consideration should be taken if qt_copy_or_install() needs to be used instead of qt_install(), which takes care of copying files from the source dir to the build dir when doing non-prefix builds. Tested with qtbase and qtsvg, developer builds, non-developer builds and static developer builds on Windows, Linux and macOS.

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). 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: 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: Fix building multi-arch universal macOS Qt Use the same approach we use for iOS, which is to set multiple CMAKE_OSX_ARCHITECTURES values and let the clang front end deal with lipo-ing the final libraries. For now, Qt can be configured to build universal macOS libraries by passing 2 architectures to CMake, either via: -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" or -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" Currently we recommend specifying the intel x86_64 arch as the first one, to get an intel slice configuration that is comparable to a non-universal intel build. Specifying the arm64 slice first could pessimize optimizations and reduce the feature set for the intel slice due to the limitation that we run configure tests only once. The first specified architecture is the one used to do all the configure tests. It 'mostly' defines the common feature set of both architecture slices, with the excepion of some special handling for sse2 and neon instructions. In the future we might want to run at least the Qt architecture config test for all specified architectures, so that we can extract all the supported sub-arches and instruction sets in a reliable way. For now, we use the same sse2 hack as for iOS simulator_and_device builds, otherwise QtGui fails to link due to missing qt_memfill32_sse2 and other symbols. The hack is somewhat augmented to ensure that reconfiguration still succeeds (same issue happened with iOS). Previously the sse2 feature condition was broken due to force setting the feature to be ON. Now the condition also checks for a special QT_FORCE_FEATURE_sse2 variable which we set internally. Note that we shouldn't build for arm64e, because the binaries get killed when running on AS with the following message: kernel: exec_mach_imgact: not running binary built against preview arm64e ABI. Aslo, by default, we disable the arm64 slice for qt sql plugins, mostly because the CI provisioned sql libraries that we depend on only contain x86_64 slices, and trying to build the sql plugins for both slices will fail with linker errors. This behavior can be disabled for all targets marked by qt_internal_force_macos_intel_arch, by setting the QT_FORCE_MACOS_ALL_ARCHES CMake option to ON. To disble it per-target one can set QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

CMake: Fix building multi-arch universal macOS Qt Use the same approach we use for iOS, which is to set multiple CMAKE_OSX_ARCHITECTURES values and let the clang front end deal with lipo-ing the final libraries. For now, Qt can be configured to build universal macOS libraries by passing 2 architectures to CMake, either via: -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" or -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" Currently we recommend specifying the intel x86_64 arch as the first one, to get an intel slice configuration that is comparable to a non-universal intel build. Specifying the arm64 slice first could pessimize optimizations and reduce the feature set for the intel slice due to the limitation that we run configure tests only once. The first specified architecture is the one used to do all the configure tests. It 'mostly' defines the common feature set of both architecture slices, with the excepion of some special handling for sse2 and neon instructions. In the future we might want to run at least the Qt architecture config test for all specified architectures, so that we can extract all the supported sub-arches and instruction sets in a reliable way. For now, we use the same sse2 hack as for iOS simulator_and_device builds, otherwise QtGui fails to link due to missing qt_memfill32_sse2 and other symbols. The hack is somewhat augmented to ensure that reconfiguration still succeeds (same issue happened with iOS). Previously the sse2 feature condition was broken due to force setting the feature to be ON. Now the condition also checks for a special QT_FORCE_FEATURE_sse2 variable which we set internally. Note that we shouldn't build for arm64e, because the binaries get killed when running on AS with the following message: kernel: exec_mach_imgact: not running binary built against preview arm64e ABI. Aslo, by default, we disable the arm64 slice for qt sql plugins, mostly because the CI provisioned sql libraries that we depend on only contain x86_64 slices, and trying to build the sql plugins for both slices will fail with linker errors. This behavior can be disabled for all targets marked by qt_internal_force_macos_intel_arch, by setting the QT_FORCE_MACOS_ALL_ARCHES CMake option to ON. To disble it per-target one can set QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

Implement developer / non-prefix builds A non-prefix build is a build where you don't have to run make install. To do a non-prefix build, pass -DFEATURE_developer_build=ON when invoking CMake on qtbase. Note that this of course also enables developer build features (private tests, etc). When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable will point to the qtbase build directory. Tests can be run without installing Qt (QPA plugins are picked up from the build dir). This patch stops installation of any files by forcing the make "install" target be a no-op. When invoking cmake on the qtsvg module (or any other module), the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build directory. The developer-build feature is propagated via the QtCore Config file, so that when building other modules, you don't have to specify it on the command line again. As a result of the change, all libraries, plugins, tools, include dirs, CMake Config files, CMake Targets files, Macro files, etc, will be placed in the qtbase build directory, mimicking the file layout of an installed Qt file layout. Only examples and tests are kept in the separate module build directories, which is equivalent to how qmake does it. The following global variables contain paths for the appropriate prefix or non prefix builds: QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR, QT_CONFIG_INSTALL_DIR. These should be used by developers when deciding where files should be placed. All usages of install() are replaced by qt_install(), which has some additional logic on how to handle associationg of CMake targets to export names. When installing files, some consideration should be taken if qt_copy_or_install() needs to be used instead of qt_install(), which takes care of copying files from the source dir to the build dir when doing non-prefix builds. Tested with qtbase and qtsvg, developer builds, non-developer builds and static developer builds on Windows, Linux and macOS.

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: Allow disabling package version check When building Qt repos, all find_package(Qt6) calls request a PROJECT_VERSION version which is set in .cmake.conf via QT_REPO_MODULE_VERSION. This means trying to configure qtsvg from a 6.3 branch using a 6.2 qtbase won't work, because qtsvg will call find_package(Qt6 6.3) and no such Qt6 package version exists. There are certain scenarios where it might be useful to try to do that though. One of them is doing Qt development while locally mixing branches. Another is building a 6.4 QtWebEngine against a 6.2 Qt. Allow to opt out of the version check by configuring each Qt repo with -DQT_NO_PACKAGE_VERSION_CHECK=TRUE. This setting is not recorded and will have to be set again when configuring another repo. The version check will also be disabled by default when configuring with the -developer-build feature. This will be recorded and embedded into each ConfigVersion file. If the version check is disabled, a warning will be shown mentioning the incompatible version of a package that was found but that package will still be accepted. The warning will show both when building Qt or using Qt in a user project. The warnings can be disabled by passing -DQT_NO_PACKAGE_VERSION_INCOMPATIBLE_WARNING=TRUE Furthermore when building a Qt repo, another warning will show when an incompatible package version is detected, to suggest to the Qt builder whether they want to use the incompatible version by disabling the version check. Note that there are no compatibility promises when using mixed non-matching versions. Things might not work. These options are only provided for convenience and their users know what they are doing.

CMake: Enforce minimum CMake version in user projects This change introduces new behavior to error out when configuring user projects if the CMake version used is too old for Qt to work with. The main motivator is the requirement of new CMake features to ensure object libraries are placed in the proper place on the link line in static builds. The minimum CMake version is computed based on whether Qt was configured as shared or static libraries. At the moment the required versions for building and using Qt are the same. The minimum versions are defined in qtbase/.cmake.conf in the following variables QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC Qt Packagers can disable the version check when configuring Qt by setting QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT. In this case it is the packagers responsibility to ensure such a Qt works correctly with the specified CMake version. User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT to disable the version check. Then it's the project's developer responsibility to ensure such a Qt works correctly. No official support is provided for these cases. Implementation notes. The versions required to build Qt are stored in QtBuildInternalsExtra.cmake whereas the versions required to use Qt are stored in a new QtConfigExtras.cmake. Also the policy range variables stored in QtBuildInternalsExtra.cmake are now regular variables instead of cache variables, to properly allow overrides per-repository. Some renaming of functions and variables was done for a bit more clarity and easier grep-ability.

Write find_dependency() calls in Qt Module config files This change introduces a new function called qt_find_package() which can take an extra option called PROVIDED_TARGETS, which associates targets with the package that defines those targets. This is done by setting the INTERFACE_QT_PACKAGE_NAME and INTERFACE_QT_PACKAGE_VERSION properties on the imported targets. This information allows us to generate appropriate find_dependency() calls in a module's Config file for third party libraries. For example when an application links against QtCore, it should also link against zlib and atomic libraries. In order to do that, the library locations first have to be found by CMake. This is achieved by embedding find_dependency(ZLIB) and find_dependency(Atomic) in Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake. The latter is picked up when an application project contains find_package(Qt5Core), and thus all linking dependencies are resolved. The information 'which package provides which targets' is contained in the python json2cmake conversion script. The generated output of the script contains qt_find_package() calls that represent that information. The Qt5CoreDependencies.cmake file and which which dependencies it contains is generated at the QtPostProcess stop. Note that for non-static Qt builds, we only need to propagate public 3rd party libraries. For static builds, we need all third party libraries. In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any scope, the targets on which the property is set, have to be GLOBAL. Also for applications and other modules to find all required third party libraries, we have to install all our custom Find modules, and make sure they define INTERFACE IMPORTED libraries, and not just IMPORTED libraries.

When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable will point to the qtbase build directory. Tests can be run without installing Qt (QPA plugins are picked up from the build dir). This patch stops installation of any files by forcing the make "install" target be a no-op. When invoking cmake on the qtsvg module (or any other module), the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build directory. The developer-build feature is propagated via the QtCore Config file, so that when building other modules, you don't have to specify it on the command line again. As a result of the change, all libraries, plugins, tools, include dirs, CMake Config files, CMake Targets files, Macro files, etc, will be placed in the qtbase build directory, mimicking the file layout of an installed Qt file layout. Only examples and tests are kept in the separate module build directories, which is equivalent to how qmake does it. The following global variables contain paths for the appropriate prefix or non prefix builds: QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR, QT_CONFIG_INSTALL_DIR. These should be used by developers when deciding where files should be placed. All usages of install() are replaced by qt_install(), which has some additional logic on how to handle associationg of CMake targets to export names. When installing files, some consideration should be taken if qt_copy_or_install() needs to be used instead of qt_install(), which takes care of copying files from the source dir to the build dir when doing non-prefix builds. Tested with qtbase and qtsvg, developer builds, non-developer builds and static developer builds on Windows, Linux and macOS.

Write find_dependency() calls in Qt Module config files This change introduces a new function called qt_find_package() which can take an extra option called PROVIDED_TARGETS, which associates targets with the package that defines those targets. This is done by setting the INTERFACE_QT_PACKAGE_NAME and INTERFACE_QT_PACKAGE_VERSION properties on the imported targets. This information allows us to generate appropriate find_dependency() calls in a module's Config file for third party libraries. For example when an application links against QtCore, it should also link against zlib and atomic libraries. In order to do that, the library locations first have to be found by CMake. This is achieved by embedding find_dependency(ZLIB) and find_dependency(Atomic) in Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake. The latter is picked up when an application project contains find_package(Qt5Core), and thus all linking dependencies are resolved. The information 'which package provides which targets' is contained in the python json2cmake conversion script. The generated output of the script contains qt_find_package() calls that represent that information. The Qt5CoreDependencies.cmake file and which which dependencies it contains is generated at the QtPostProcess stop. Note that for non-static Qt builds, we only need to propagate public 3rd party libraries. For static builds, we need all third party libraries. In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any scope, the targets on which the property is set, have to be GLOBAL. Also for applications and other modules to find all required third party libraries, we have to install all our custom Find modules, and make sure they define INTERFACE IMPORTED libraries, and not just IMPORTED libraries.
