[CMake] surprising new behaviour of cmake cvs - object filecreation

This is intentional. Basically the old behavior was considered a bug by most
people so we fixed it. The problem is in cases like:

SET (SRCS ../lib/foo.c ../extra/foo.c)

The two foo.o files clobber each other if they are in the current directory.
