[CMake] Control Object code destination?

[Mike Jackson]

I don't get what you are trying to do. If you are compiling for 4  
platforms (as am I) are you compiling from some sort of shared drive  
or network drive that all 4 platforms have concurrent access to? I  
don't understand how the object code from a windows build could be  
used on an OS X build? Or am I missing something? Generated Header/ 
source files maybe?

Maybe some more information about your setup might help us help you.

Just as a point of reference I think one way might be to have a  
central cvs (or svn or whatever) and when your code compiles on the  
first system, commit the changes, then move to the next, cvs update,  
compile, and so on and so forth..

Cheers
