How does the actual linker call look like? (make VERBOSE=1)

Can you check wether link_directories(${KDE4_LIB_DIR}) helps? Thats
something that is needed for CMake 2.6 support anyway and if we have a
need for this with cmake 2.4 it may speed up getting this into svn.


You will be awarded some great honor.
