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: 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).

Add initial support for CMake "Ninja Multi-Config" generator This allows doing debug_and_release builds with Ninja on all platforms. The "Ninja Multi-Config generator" is available starting with CMake 3.17. Desired configurations can be set via CMAKE_CONFIGURATION_TYPES. Possible values: "Release, Debug, RelWithDebInfo, MinRelSize". For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug". The first configuration is the 'default' configuration which is built when calling ninja with no arguments. To build all targets of a certain configuration use "ninja all:Release" or "ninja all:Debug". To build all targets in all configurations use "ninja all:all". Note that the first configuration influences which configuration of tools will be used when building the libraries for all configurations. In simple terms, when configured with -DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc is used by AUTOMOC. When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release" the debug version of moc is used by AUTOMOC. Framework builds and Ninja Multi-Config don't currently work together due to multiple bugs in CMake, which ends up generating an invalid ninja file with duplicate rules. There are also issues with placement of the debug artifacts. This will be handled in a follow up patch after CMake is fixed.

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().

Add initial support for CMake "Ninja Multi-Config" generator This allows doing debug_and_release builds with Ninja on all platforms. The "Ninja Multi-Config generator" is available starting with CMake 3.17. Desired configurations can be set via CMAKE_CONFIGURATION_TYPES. Possible values: "Release, Debug, RelWithDebInfo, MinRelSize". For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug". The first configuration is the 'default' configuration which is built when calling ninja with no arguments. To build all targets of a certain configuration use "ninja all:Release" or "ninja all:Debug". To build all targets in all configurations use "ninja all:all". Note that the first configuration influences which configuration of tools will be used when building the libraries for all configurations. In simple terms, when configured with -DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc is used by AUTOMOC. When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release" the debug version of moc is used by AUTOMOC. Framework builds and Ninja Multi-Config don't currently work together due to multiple bugs in CMake, which ends up generating an invalid ninja file with duplicate rules. There are also issues with placement of the debug artifacts. This will be handled in a follow up patch after CMake is fixed.

Add initial support for cross-building to iOS Tested locally with the following configurations: - iOS device builds (arm64) - iOS simulator builds (x86_64) - iOS simulator_and_device builds (fat arm64 and x86_64 archives) All iOS builds currently require a custom vcpkg fork which contains fixes for building the required 3rd party libraries. qtsvg, qtdeclarative, qtgraphicaleffects and qtquickcontrols2 have also been tested to build successfully. simulator_and_device builds are also supported, but require an umerged patch in upstream CMake as well as further patches to vcpkg.
