The RPATH thing only enabled using smokegen from within the build
directory. When it's installed, the RPATH is still removed (as you can
see in your 'make install' output which you've posted). Either set
LD_LIBRARY_PATH to point to your lib/ directory or add it to
/etc/ld.so.conf. I guess you could also add some CMake option which
prevents removal of RPATH. But off the top of my head, I don't know how.
