I'd also be interested to know if KDE4_ENABLE_FINAL is worth it. Getting rid 
of it would mean one less reason for kde4_add_{library,executable} to exist. 
I'd always wondered why we needed our own prefixed macro, and can't just use 
the cmake one.

If it is worth it, can we try to get it (or something better) upstream to 
cmake. enable_final doesn't/can't cat the moc files together with the rest, 
whereas that could be done by cmake at the right time after the dependencies 
have been worked out.
