I am trying to enable i18n support on slicer, and it is generate “fr” translation files by default after enable Slicer\_BUILD\_I18N\_SUPPORT and Slicer\_UPDATE\_TRANSLATION.  
Then I changed “fr” to “zh” in CMakeList.txt and it stop generate new translation files, and even I changed it back to “fr” it is still not working to update or generate new “fr” translation files.

How can I force cmake to generate new or update exist ts files?  
Is there any place to cache “ts” files which prevent cmake to generate/update ts files?

Solved by rebuild vs solution.
