CMake: QT5_CREATE_TRANSLATION how to prevent delete existing ts file during clean

[AnatolyS]

I use QT5_CREATE_TRANSLATION to keep my ts file in actual state. It is very useful. But when I call make clean my ts files are cleaned also. It is because of

add_custom_command(OUTPUT ${_ts_file}
            COMMAND ${Qt5_LUPDATE_EXECUTABLE}
            ARGS ${_lupdate_options} "@${_ts_lst_file}" -ts ${_ts_file}
            DEPENDS ${_my_sources} ${_ts_lst_file} VERBATIM)

add_custom_command(OUTPUT ${_ts_file}
            COMMAND ${Qt5_LUPDATE_EXECUTABLE}
            ARGS ${_lupdate_options} "@${_ts_lst_file}" -ts ${_ts_file}
            DEPENDS ${_my_sources} ${_ts_lst_file} VERBATIM)

To copy to clipboard, switch view to plain text mode 

inside the QT5_CREATE_TRANSLATION function.

Is there way to prevent ts file deletion?
