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: Don't use libraries in /usr/local by default on macOS qmake builds of Qt don't use libraries in /usr/local because the path is not considered a system path. Only the SDK path should be used as a source of system libraries. We should do the same for the CMake builds, which involves a couple of things. Tell CMake not to consider /usr/local (and a bunch of other paths) as system prefix paths. Disable pkg-config usage which by default is not used in qmake Windows and macOS builds.

The downside to this is that a lot of warning messages will be printed that the pkg-config package can not be found. The pkg-config feature needs to be computed in QtBuildInternals before qtbase/src/configure.cmake, because it's too late to do it in that file where a few qt_find_package calls already exist. The feature value is also saved to QtBuildInternalsExtra, to make sure that pkg-config is disabled whenever building another repo. System prefix adjustment is done by removing paths from CMAKE_SYSTEM_PREFIX_PATH. Ideally we would remove also /usr as a path, to match what qmake does, but that breaks find_program() calls for perl, python, etc. We have to make sure that qt_find_package does not look in PATH when looking for packages, which is the default behavior, because PATH on macOS most likely contains /usr/local. One last curiosity for future generations is that CMake 3.18+ has merged a change to prioritise SDK locations over regular /usr/lib.

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.

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.

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: Allow sqldriver plugins to be built as standalone This patch allows all the sqldrivers to be built as a standalone project. It is not possible to build each plugin separately due to the configuration features definition being located in the sqldriver's folder CMakeLists.txt.

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.

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.

Fix linking of examples Provide add_qt_gui_executable() as function in our public API that takes care of automaticWinMain linkage. We can use this in the future to encapsulate similarplatform-specific behavior and adjustments, such as module generation onAndroid. In order for the examples to see the function in Qt5CoreMacros, three more additional fixes were required: * Do the build_repo_end() call _before_ attempting to build the examples, as we need the build_repo_end() to include QtPostProcess and complete the creation of all the target config files. Otherwise the find_package() calls in the examples see something incomplete. * Add more QT_NO_CREATE_TARGET guards * Always call find_dependency on the dependencies, regardless of the target creation mode. This way a find_package(Qt5 COMPONENTS Widgets) will still load Qt5CoreMacros.

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.

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.

Allow building the tests directory as a standalone CMake project At the moment, Coin builds tests as a separate qmake invocation against an installed Qt. We need to support the same with CMake. Change the tests subdirectory to be a standalone CMake project when CMake does not detect an existing QtTest target while processing the subdirectory.

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: 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).

# Because CMAKE_INSTALL_RPATH is empty by default in the repo project, examples need to have
# it set here, so they can run when installed.
# This means that installed examples are not relocatable at the moment. We would need to
# annotate where each example is installed to, to be able to derive a relative rpath, and it
# seems there's no way to query such information from CMake itself.

CMake: Add qt6_add_plugin public API This patch adds a publicly callable qt6_add_plugin() API to create plugins. This API is meant to cover cases such as the plugandpaint example. This patch also renames qt_add_plugin to qt_internal_add_plugin in order to avoid clashes with the public API. To avoid breaking the existing projects, a compatibility wrapper function is enabled by default unless QT_DISABLE_QT_ADD_PLUGIN_COMPATIBILITY is specified.

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.

Android: Final changes for APK generation Generate the ${MODULE}-android-dependencies.xml for the androiddeployqt tool. This will ensure all the right plugins and dependencies are packaged when generating the apk. This change also changes the visibility for executable to default/public. Not having this will cause the application to crash as we can't locate main() in the executable (shared library). Additionally pro2cmake conversion script has been updated to perform the required conversions for the Android settings. Finally, the 6 projects in QtBase that have Android dependencies have been updated with the new script and the step that produces the xml files in run at the end in QtPostProcess.cmake.
