In general, that's not easy with Xcode. Have you considered creating  
separate build targets for each OS target? Then it's just a matter of  
setting the library paths for each build target, assuming you have the  
different versions in different places.

The only other hack that I can think of is to define a library path as  
something like -L$(SRCROOT)/libraryLink. Then you could add a script  
build phase to your target whose script examines the OS that is  
selected (Xcode exports all the settings to the environment before  
running your script) and creates  the libraryLink symlink to point to  
the proper directory. That symlink would then be followed in the link  
phase.
