Something is really strange here.  I don't understand how this could 
happen.   It would be really good at this
point if you could create a small example project that shows this 
problem and post it so I can take a look.
Really you should be using full paths to libraries and not 
LINK_DIRECTORIES anyway.

Something like this:
target_link_libraries(foo optimized /full/path/to/relbuild/bar.lib debug 
/full/path/to/debugbuild/bar.lib)

The odd part is that if you do not use full paths then it should never 
relink because of a library
changing.   Something else is different in your cmakelist file.  Again, 
please create a complete
example that shows the problem.
