Then use "debugfull" as CMake Build Type, thats a special one provided
by FindKDE4Internal.cmake and sets -O0 -g3 explicitly. The
FindKDE4Internal.cmake file is also the culprit of setting -O2 -g in the
cmake commandline. Unfortunately whoever wrote that piece implemented it
in a way that it always overwrites whats set in the cache...
