Translation is not updated by qt5_create_translation

[l3u_]

Hi all,

I just noticed one thing about a (still Qt 5) project: My translations are created initially, but they are not updated when I cange something in my TS file.

In my CMakeLists.txt I have:

find_package(Qt5LinguistTools)

and later on

if(Qt5LinguistTools_FOUND)
    set(TS_FILES ${CMAKE_SOURCE_DIR}/res/muckturnier_de.ts)
    set_source_files_properties(${TS_FILES} PROPERTIES
                                OUTPUT_LOCATION ${CMAKE_BINARY_DIR}/share/muckturnier)
    qt5_create_translation(QM_FILES ${muckturnier_SOURCES} ${TS_FILES}
                           OPTIONS -pluralonly -locations none)
    add_custom_target(Localization ALL DEPENDS ${QM_FILES})
endif()

As said, the translation is updated if I start with an empty build directory – but when I change something in the sources and rebuild, nothing happens concerning the translation. After wiping the build directory and building from zero again, the changes are incorporated.

I'm not really a CMake pro … obviously, I'm missing something here.

Thanks in advance for all help!
