Yes, that is exactly the problem.

Some generator expressions do support recursion.  While some
checks may be useful there, I do not think that is the right
place to solve this particular problem.

The basic cmTarget methods that compute the output directory and
name need to check for recursion themselves and at least not crash
on it.  I explained the needed refactoring a few messages back in
this thread.  This will ensure that other future changes do not
find another way to introduce recursion.

Thanks,
