The UNIX Makefile generator does not yet implement the debug postfix 
setting simply because no one has contributed it and we have not yet had 
a need for it.  Since this generator supports only one configuration per 
build tree anyway, you should be able to specify different paths for the 
debug/optimized flag:

TARGET_LINK_LIBRARIES(... debug ${FOO_DEBUG_LIBRARY}
                           optimized ${FOO_RELEASE_LIBRARY})

Then just make sure the two variables are set to point to separate build 
trees of the original library in your outside project.

You may also report this limitation to the bug tracker:
