[REG 6.3.1 -> 6.3.2] qt_add_resources with .qm translation files no longer rebuild generated .qrc when .qm files change

Hello,

With following CMakeLists.txt:

set(TS_FILES myapp_fr.ts)

qt_add_executable(${PROJECT_NAME}
    [...]
)

qt_add_translations(${PROJECT_NAME}
    TS_FILES ${TS_FILES}
    SOURCES ${PROJECT_SOURCES} ${PROJECT_HEADERS} ${PROJECT_QML_FILES}
    QM_FILES_OUTPUT_VARIABLE QM_FILES
)

qt_add_resources(${PROJECT_NAME} "translations"
    PREFIX "/i18n"
    BASE "${CMAKE_CURRENT_BINARY_DIR}"
    FILES "${QM_FILES}"
)

[...]

Here is what happen with Qt 6.3.2:

• When ts file changes, qm file is properly refreshed
• However, qrc_translations.cpp is no longer rebuilt by "rcc"

It was previously working properly with Qt 6.3.1.

Issue seems to be related to a recent regression of Qt6LinguistToolsMacros.cmake, as commenting out the following code from qt6_add_lrelease fixes the issue:

        set_source_files_properties("${qm}" ${scope_args} PROPERTIES
            _qt_resource_target_dependency "${target}_lrelease"
        )

When the code above is present, qt_add_ressources will end up adding lrelease dependency but will no longer add the ${qm} file itself to dependencies, which leads to the issue.

Best regards,
Louis
