cmake_minimum_required(VERSION 3.16)
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.

CMake: Get tests/auto/cmake tests working The tests/auto/cmake project can be configured separately as a standalone project with qt-cmake, or as part of the overall qtbase standalone tests. To do that a bunch of things were done - Ported all Qt5 strings to Qt6 - Replaced in all projects the use of add_definitions and include_directories with a target based approach, except for 2 tests where we check that the old-style approach works, otherwise the tests would file - Removed some (possibly unneeded) EGL / OpenGL tests - Fixed some C++ code - Added setup code to tests/auto/cmake/CMakeLists.txt to figure out which modules are available and should be tested - Fixed Qt6CTestMacros.cmake to be loaded by Qt6Core - Removed the CMake tests to not be run in qmake builds of Qt because they would fail anyway - Enabled the CMake tests to be part of standalone tests - Disabled auto-passing of the C and CXX compiler cache vars when cross-compiling so that the tests can somewhat pass on boot2qt. This is the issue we encountered in e2b2cd9397c76e91ac1ebe493bcac7696767c02e - Ultimately disabled tests for boot2qt, because the -rpath-link flag is not generated by CMake for some reason. - Added code to setup the environment when running an executable that was built as part of the test, so that the proper Qt libraries are found. This handles both the standalone tests case and separate project case. The remaining unported tests are test_import_plugins which requires quite a bit of work to get some modules and plugins built that were done as part of the qmake .pro files, test_plugins that checks some Network plugins which I'm not sure about, and test_add_big_resource which doesn't work with namespaced builds and there's no good way of detecting those at the moment either.
