The KDELibsDependencies.cmake file should indeed be installed to lib/, not 
into share/. That was a mistake in the beginning and I didn't dare to change 
it yet (also nobody really complained).
So this is something we will do.

But I don't think this is all.
What should kde4-config say ?
hammer:~$ /opt/kdelibs/bin/kde4-config --path lib
/home/alex/.kde/lib/:/opt/kdelibs/lib/
hammer:~$

If a 32bit- and a 64bit version of kdelibs are installed to the same prefix, 
one kde4-config will overwrite the already existing one. How does kde4-config 
know whether you want the 32- or 64-bit library directory ?

I guess there are more things.
