Can you run make with VERBOSE=1 and give as the output please?

To me it looks like, that cmake discards the library directory and links 
with -lboost_filesystem instead of the fullpath. This happened in my 
environment whenever the environment variable LIBRARY_DIR contains the 
boost library directory.

Nevertheless, you should unset LIBRARY_DIR with cmake. Otherwise, the 
compiler gcc will treat the folders in this variable as system folders.
