Problems with translation files with Qt 6.8

KejPi

Hello, I am currently facing some issue that was not present in 6.7.3. It is related to translation files, when application links I get this error:

duplicate symbol 'qCleanupResources_AbracaDABra_translations()' in:
    /Users/kejpi/Devel/AbracaDABra/build/Qt_6_8_0_for_macOS-Debug/gui/CMakeFiles/AbracaDABra.dir/AbracaDABra_autogen/JYUKLDW5FZ/qrc_AbracaDABra_translations.cpp.o
    /Users/kejpi/Devel/AbracaDABra/build/Qt_6_8_0_for_macOS-Debug/gui/CMakeFiles/AbracaDABra.dir/__/.qt/rcc/qrc_AbracaDABra_translations.cpp.o
duplicate symbol 'qInitResources_AbracaDABra_translations()' in:
    /Users/kejpi/Devel/AbracaDABra/build/Qt_6_8_0_for_macOS-Debug/gui/CMakeFiles/AbracaDABra.dir/AbracaDABra_autogen/JYUKLDW5FZ/qrc_AbracaDABra_translations.cpp.o
    /Users/kejpi/Devel/AbracaDABra/build/Qt_6_8_0_for_macOS-Debug/gui/CMakeFiles/AbracaDABra.dir/__/.qt/rcc/qrc_AbracaDABra_translations.cpp.o

I have this in CMakeLists.txt:

set(TSFILES
    l10n/${TARGET}_cs.ts
    l10n/${TARGET}_de.ts
    l10n/${TARGET}_pl.ts
)
qt_add_translations(${TARGET} TS_FILES ${TSFILES}
    LUPDATE_OPTIONS "-noobsolete"
)

If I comment out qt_add_translations macro then it links file but translation does not work.

I have also found out that if I keep qt_add_translations but remove qt_finalize_target(${TARGET}) it works too.
I need qt_finalize_target(${TARGET}) to make "allow location permissions" dialog working on macOS.

Problem is not macOS related, the problem is on Linux too: https://github.com/KejPi/AbracaDABra/issues/171

Everything is working fine with Qt < 6.8.
Do you have any idea how to fix it?

Thanks for pointing that out, that is exactly the issue I have.
According to related bug report I have removed

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

and replaced them by:

qt_standard_project_setup()

This seems to work for Qt 6.8.0 and also lower version (tested with 6.5.3).

I am marking this issue as solved, thank you!
