[CMake] FindQt4 patch

[Tanner Lovelace]

Greetings,

The current FindQt4.cmake script has a small problem where it
does a FIND_PACKAGE(X11 ...) if it's on Unix.  The problem
with this is that OS X is considered to be Unix but Qt on OS X
can be either X11 or native mac without X11 at all.

So, this patch checks for the actual window system defines
set by Qt and only does the X11 check if the Qt found is an
X11 Qt.  In addition, the symbols should be exported for others
to use them to check for the same thing accordingly.

Please look over the patch and if it looks good, could one of
the developers apply it?

Thanks very much!

Cheers,
Tanner Lovelace
