Please update kdelibs/cmake/modules/FindGSSAPI.cmake, I committed a patch so 
that it shouldn't find the build host executable anymore.

You should only need something like QT4_PREFIX, all the stuff for KDE should 
now be found correctly.

This should work now with current kdelibs and current cmake.
FindKDE4.cmake should now only find kde4-config from the target, not from the 
build host, and then simply reuse its location instead of querying it for the 
path.

Please try that again with a fresh buildtree, it should really work now.
If it doesn't, please post the detailed problems.
