[cmake-developers] FindQt4 DBus framework problem on the Mac

[David Cole]

I still get bit by issues with QtDBus when building VTK with Qt
support on my Mac... It gets "found" as a .framework, but there's not
actually a library inside the framework folder, so link errors occur.
It would be fine if it simply didn't get found.

I waste some time every few months when I rebuild VTK again, encounter
this problem, then figure out how to fix it manually one more time,
and then forget about it again. This patch would allow me to NEVER
HAVE THE PROBLEM AGAIN.

Would the attached patch be reasonable to put into FindQt4, or should
we actually build similar functionality into the find_library code
internal to CMake?


Thanks,
David
