[CMake] Cross-compiling with FindQt4.cmake

[Clinton Stimpson]

To cross-compile Qt apps, you still need to be able to run at least uic, 
moc, and maybe other tools.

I've done it before (way back when cross-compiling support was first 
added to cmake).
What I did was compile Qt for the target platform, and again for the 
native platform using the same install prefix for both.  I installed the 
target platform Qt, then copied qmake/uic/moc/etc... from the native one 
into the first installation.

Is there an official way to cross-compile Qt that is different than what 
I did?
With that, could you use qmake generated makefiles (which assumes you 
can run qmake natively)?
