I updated cmake to use CMAKE_PREFIX_PATH instead of CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH.
There were some expressions in kde that required CMAKE_PREFIX_PATH, and now they are not anymore
a special case.
I updated most kde-4.4 files to point to kde-4.4.0 sources instead of 4.3.4 .

I patched properly their own copy of cmake findqt4 module, the same way as we had to
do in the cmake expression.
The findqt4 patch we have is already filled in the cmake buglist, but it seems it is
still not solved in in cmake 2.8.0
