I'm wondering how you want to "share" targets, maybe you can give some more information about this? Usually I would use variant 
directories to create a different (set of) executable(s). So the targets, like programs and libraries, would differ by design...and 
therefore cannot be shared.

This leaves me a bit puzzled at the moment...
