OK, well, this has to be something in the Slicer cmake code, as CMake 
does not go around adding libraries.  But, I would suggest that you look 
at the CMakeCache.txt as CMake stores library depends in this file.  You 
might be able to figure out where this is coming from.   If you want you 
can email me the build.make and CMakeCache.txt off the list, and I might 
be able to help.
