Yes. CMake should be able to take care of this for you.

Yes. My own solution (involving a bash script that gets configured by  
CMake) can be found at <http://titanium.imts.us/viewvc/Task_7/ 
MXATools/Resources/OSX_Tools/>. The actual project is at <http:// 
titanium.imts.us/viewvc/Task_7/MXATools>.
