Embed the translation files in the binary

Browse source 
If a translation file exists in a "translations" directory located in
the same directory as the binary, it is used in priority (this can be
useful when working on translations as you don't have to recompile the
whole program all the time), and if no such file is found the embedded
translation file is used (if it exists).
