[KPhotoAlbum] build woes (from git on openSuse12.2) - "This file was generated using the moc from 4.7.4. It cannot be used with the include files from this version of Qt."

[Miika Turkia]

Just a quick comment before reading the mail properly (that'll have to
wait until after work, if problem is not solved by then). Try to build
the whole thing in a different directory. e.g.
- mkdir build (under kphotoalbum sources)
- cd build
- cmake <required parameters> ..

and normal make after that. This way there is nothing left from the
compile on different system. And cleaning the compile stuff is easier
with rm :D
