Here Here!

I've had to add custom post-build rules for this issue before too. 
Other users I know of in the OSG project have resorted to trickery with 
the PREFIX target option to try to work around this problem.

I've filed this as bug #5805 (feature request) in the bugtracker.

Implementing this modification for the Visual Studio generators is 
trivial (I did it two weeks ago by coincidence when I came across this 
issue yet again).  I had a look at the Makefile and Makefile generators 
that same day though and nearly had a stroke :).  Provided someone could 
give me some pointers as to where to start I probably could add the 
support for this.
