I looked a bit around cmFindPackage.
It has a parameter "CONFIGS", it has a "Config mode" and the documentation and 
error messages use "configuration file".
So, I'm not that sure that using "PACKAGE" instead of "CONFIG" is really 
better (the branch I pushed uses "PACKAGE", but I could change this again).
