In qm_add_translation, the .ts file is not updated automatically

This code doesn't work, unable to update the ts file.
add_custom_command instructions are executed in the build phase, which is not very friendly to development, can it be generated in the cmake phase.
Or control whether an update is required through a variable.Because this step may be time -consuming.
It seems that you are not completely aware of how the translation function works. We cannot update the ts files at configure phase because source files cannot be modified during configure phase while ts files are also a kind of source file. You can set the target name when calling qm_add_translation(xxx ...) and a target named xxx_lupdate will be created. After configure phase, you can run cmake --build build --target xxx_lupdate to update the ts files. I also add an exception here, when you set the option CREATE_ONCE, qm_add_translation will generate the ts files right away if the ts files don't exist, provided all source files are available at configure phase, sometimes there are future source files generated at build phase.
