True. I have a task for this on the framework l10n wiki page

There is a new function in ecm to build .qm files from the .po files and
generate a .cpp file to autoload the translation. I modified the root
CMakeLists.txt of all qt-based frameworks to use it if a "po" directory
exists.

I experimented with this today and made the function work even if the po
directory does not exist. In this case it only creates the .cpp file
(these changes have not been committed yet).
Having thought about it, I prefer it this way in all cases: I don't like
much the idea of having different code produced depending on whether the
po directory is there or not. Always generating the .cpp file feels
better.

Sorry, I don't understand what you mean with the "templates folder".
