[CMake] Good sample code for finding and using os x frameworks?

[Andrew Wagner]

Hello-

I'm writing some software that I'm trying to keep as portable as  
possible, but alas will need to use some apple-specific code to query  
mouse position.   Are there any good examples for the current best  
way of doing this?  i.e. should my source have #include <framework/ 
header.h> or just #include<header.h>?  Are there modules for finding  
the standard os x frameworks, or should I hard code the paths in my  
CMakeLists.txt?  I hunted around a lot for this, but all I could find  
were discussions on the mailing list that did not seem to imply any  
sort of consensus yet, and were discussing future development.  I'm  
still new to cmake, so please forgive me if I'm not even asking the  
right question.

For the time being, I don't care about creating frameworks; just  
using existing ones supplied by apple.

Thanks,
Drew
