That doesn't look right.
CMAKE_LIBRARY_OUTPUT_DIRECTORY is the directory where the library is built, 
not the directory where it is installed to.
Is libMUONevaluation.so actually getting installed or is that an old version 
which is already in /usr/local ?

Maybe it is not and the executable doesn't find it then, because it has not 
been installed ?

Also, I thought on OSX it's DYLD_LIBRARY_PATH, and not LD_LIBRARY_PATH. AFAIK 
you also don't have an RPATH, but instead INSTALL_NAME_DIR.
