I would do a "make VERBOSE=1" and verify that CMake is linking your
executable against what you think it should be linking against.

If that was not the problem, I'd have a second look at your library
implementations and double check that you're compiling and linking what you
think you're compiling and linking.  You can use "nm" or some other tool to
inspect the generated shared libraries and ensure that the proper symbols
are defined (or not defined).
