Build KDE on Mac OS with Qt Framework (Patch for FindQt4.cmake)

[younker]

I have tried some times to build KDE svn version on my Mac OS X, but
everytime I failed on finding the symbol Q_WS_MAC when doing
configuration with my Qt4 framework installation.

Today, I did some test and found maybe the problem is caused by the
installation path of Qt4, I installed it to /opt/Qt4 which is not the
default framework path, so when cmake check the symbol, it always fail
on link the framework(maybe), so I modified the FindQt4.cmake file and
make it use QT_LIBRARY_DIR as the framework path when link the library.

Below is a patch that I made for FindQt4.cmake of strigi, it does work.
