[CMake] cmake cvs breaks kde4 builds

[Aleix]

Hi andreas,
I am compiling KDE with the cmake-cvs version.

I had the same problem when I switched and, IIRC, I had to (nuke every
builddir and) recompile whole KDE because of this -lgeneral thing, but
this was back in the summer so I think it is not a new issue.

Bye!
Aleix
