If you actually create this minimial example does the problem still 
occur?  Does the "foo.lib" actually exist in the appropriate place when 
the link error occurs?

If the paths are already listed then this shouldn't be necessary.  Also 
you should never have to use ${CMAKE_CFG_INTDIR} in a LINK_DIRECTORIES 
command because CMake does it automatically for the VS generators.

The intention of CMake is that there should be no special needs to 
support multiple generators.
