CMake: Fix resource objects story in static prl files The CMake build of Qt intends to improve the developer experience in regards to static Qt builds and Qt resource files. Specifically with a CMake build of Qt, Qt developers don't have to manually call Q_INIT_RESOURCE anymore. For details see the following commits e343affd6345ef8db041789a96016c3a84830dc9 e817ac3d68295fc0670ccede4df08bf1c7e627d2 4ab54320817ebbb465af343514d21139a654aed3 The last commit's implementation is incomplete though. To ensure successful linking, each target's prl file should contain not only the resource object files that are assigned to the target, but also all resource object files of the target's dependencies. To achieve that, qt_collect_libs will now recursively collect all resource object files assigned to the QT_RCC_OBJECTS property of each dependency. Note this implementation is still incomplete. We do not export rcc object file information in the CMake Targets files. That means that when configuring qtdeclarative in a non-top-level build, the generated Qml prl file will not contain references to Core's mimetypes resource object file, etc. So with the current change, only the object files that are part of the current CMake configuration build are tracked. Exporting the resource object files locations proves in a format usable for prl files proves to be difficult (due to CMake not supporting exporting genexes in random properties) and will have to be addressed in a separate change.

CMake: Make qt_internal_walk_libs available in public projects Needed for the upcoming static plugin mechanism, where we have to extract the list of Qt module dependencies of a target and then extract the plugins associated with those modules. To do that we need to recursively collect the dependencies of a given target. Rename the moved functions to contain the __qt_internal prefix. Also rename the existing QtPublicTargetsHelpers.cmake into QtPlatformTargetHelpers.cmake to avoid confusion with the newly introduced QtPublicTargetHelpers.cmake.

CMake: Fix resource object file paths in prl files for prefix builds Before this change, the prl files always assumed that resource object files are installed into $qt_prefix/lib when doing a prefix build. That was true for qt_internal_add_resource calls, but not for qt6_add_qml_module and qt6_target_qml_files. Change qt_internal_record_rcc_object_files to take a new required INSTALL_LOCATION argument. The argument takes a path relative to CMAKE_INSTALL_PREFIX. Modify __qt_propagate_generated_resource to save the relative path of the generated resource source file, which will be used in the computation of the final resource object file location. This is needed because the Qml resource functions place the source files in a different directory layout, e.g. .rcc vs .qmlcache Modify qt_generate_prl_file to prepend $$[QT_INSTALL_PREFIX]/ instead of $$[QT_INSTALL_LIBS]/ for the resource install paths. A follow up patch is done in qtdeclarative to pass the new INSTALL_LOCATION argument from the Qml CMake functions.

CMake: Fix generation of prl files for non-qtbase modules Previously we determined if a library represented by an absolute path is a Qt module by checking if it's located in the build dir of the current repo. That is not sufficient for non-qtbase prefix builds, where a Qt module might link against both a module in the current build dir and in the prefix dir. Detect such cases, and rewrite the absolute paths to relocatable paths (either framework flags or paths starting with $$[QT_INSTALL_LIBS]. This should fix building examples with qmake that use QtQuick. Fixes: QTBUG-87840 Change-Id: Icaf8f1a7c66292c80662fd0d5771a5a1628a9899 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>

CMake: Fix generated prl and pri files for MSVC In MSVC static build, if we build Qt with 3rdparty library (e.g. zstd), cmake will add"zstd" (without "-l" prefix) to Qt6Core.prl. Then we use this Qt to build a qmake project, compilation will fail due to missing zstd.obj. Without "-l" prefix, qmake will treat "zstd" as an object file instead of a library. Library names in qt_module.pri and qt_lib_*_private.pri are also missing "-l" prefix. This is because on most compilers, CMAKE_LINK_LIBRARY_FLAG equals "-l". But on MSVC, it is an empty string. So we should pass "-DLINK_LIBRARY_FLAG=-l" for MSVC. Also add "-L/path/to/library" if the library path is not in default linker search directories. This will write un-relocatable paths to prl files only when using 3rdparty libraries to build Qt statically. Usually it's not a problem. In addition, CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is also empty on MSVC. So The third argument of "$<FILTER>" is empty, it is an invalid generator expression. This means no include dir will be written to qt_module.pri and qt_lib_*_private.pri on MSVC. So only use "$<FILTER>" when CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is not empty.

CMake: Fix generation of prl files for non-qtbase modules Previously we determined if a library represented by an absolute path is a Qt module by checking if it's located in the build dir of the current repo. That is not sufficient for non-qtbase prefix builds, where a Qt module might link against both a module in the current build dir and in the prefix dir. Detect such cases, and rewrite the absolute paths to relocatable paths (either framework flags or paths starting with $$[QT_INSTALL_LIBS]. This should fix building examples with qmake that use QtQuick. Fixes: QTBUG-87840 Change-Id: Icaf8f1a7c66292c80662fd0d5771a5a1628a9899 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
