Well, you can't use DEPRECATION, as that doesn't exist in CMake 2.8.12. Otherwise, I think this is sensible. I'm definitely in favour of following the gettext_process_po_files() signature.

I'm inclined to remove ECMCreateQmFromPoFiles.cmake entirely before 1.0, though (but maybe leave it in with an AUTHOR_WARNING for beta2, just to cause fewer issues for people updating only parts of their tree). It's not like anything other than some of the frameworks has made use of it.

One thing I will say is: unit tests, please! See tests/ECMInstallIconsTest/ for inspiration.
