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: Allow usage of QtStandaloneTestTemplateProject as package component Currently in order to compile a Qt6 test standalone one needs to use the qt-cmake-standalone-test script which will load the Qt6BuildInternals/QtStandaloneTestTemplateProject/CMakeLists.txt project with the current test source directory to create a complete CMake project. This commit will allow a test to have these lines at top: cmake_minimum_required(VERSION 3.16) if (NOT QT_BUILD_STANDALONE_TESTS AND NOT QT_BUILDING_QT) project(a_qt_test LANGUAGES C CXX ASM) find_package(Qt6BuildInternals COMPONENTS STANDALONE_TEST) endif() and be standalone and work with any IDE capable of loading CMake projects.
