That was not true when I implemented this the first time.  We have a 
test in CMake that counts on library ordering and it failed.

OK, sounds good...

If you can get all the CMake tests to pass with these changes, I would 
be very happy to get rid of the extra stuff.  It may have changed, but 
when I first did the implementation, it was required to do it the way it 
is. That said, I have not revisited this stuff since Xcode 1.5, so 
things may have changed for the better.
