Have to clear out entire build to see translation update

I'm adding translations to Japanese and German to my application.  So I added these lines into my CMake file for my project:

# Add files for translations
qt_add_translations(PSRayTracing_QtUI
  TS_FILES
  i18n/qt_ui_en_US.ts
  i18n/qt_ui_de_DE.ts
  i18n/qt_ui_ja_JP.ts
)
add_dependencies(PSRayTracing_QtUI release_translations)

When I change the locale of my device (e.g. Linux Desktop, Android, or iOS), I do see my app loading the correct translation.  But if a change an entry in a `.ts` file, I'm not seeing the change applied until I've cleared out the entire build  (e.g. via a `cmake --build . --target clean`).
