I read that on the online Documentation.html for cmake and tried it out yesterday to
see if that was the case.  It did find the frameworks, but it found them as
"/Library/Frameworks/QtXXX.framework/QtXXX" and didn't have the "-framework" part at
the beginning of the string like the FindQt4.cmake in KDE's cvs did, so I went this
route.

I'll play with it some more and see if I can make it work, though.
