Hey that was an improvement already; initially it said "KDE4 not found" or something like that :)

Well I didn't add a line like "Did you forget to install kdelibs first?", because
it could also be that the user installed kdelibs, but didn't adjust the PATH,
so another kde-config is found, which points to another directory.
That's why I thought it would be clear enough to simply point out the paths
that we're looking into. If cmake/modules/FindKDE4Internal.cmake isn't in this
list of paths, then obviously
- kdelibs hasn't been installed at all
or
- kdelibs hasn't been installed there.
   (which means either that PATH is wrong, or that kdelibs was installed to the wrong place)

Hmm, ok, the piece of information that might be missing to people is that
FindKDE4Internal is actually installed by kdelibs. I'm fine with adding that,
but since "did you forget to install" isn't the only possible reason for the problem,
I'm not sure how.
