kdelibs doc common build problem

Serghei, I almost have kdelibs built, but from what I can tell the common/ symbolic link in the documentation directories is not being created. As one example, a symbolic link would normally be present in /opt/trinity/share/doc/kde/HTML/en/kspell/common, pointing to the /opt/trinity/share/doc/kde/HTML/en/common directory. This is so that the KHTML-based documentation renderer can find the needed graphics and style files. I would try to fix this myself, but I lack the requisite CMake knowledge to do it correctly. Thanks! Tim
