[CMake] How can I avoid the addition of Debug/Release to the link path?

This has to be this way, or the cmake generated projects will not be 
able to find
libraries in other projects of the same build type.  Can someone explain 
the issue
with this?   We are using this for VTK and several other larger 
projects, and
it works fine.
