Sorry for the late reply. I am not sure, whether you have used the provided build script? It seems that you did not copy the generated liborb_slam2_lib.so file to the system directory. Check the build_catkin.sh script - there is an command making the file visible during compilation:

sudo cp liborb_slam2_lib.so /usr/local/lib

I've just updated the build script and the readme. The installation process should finish flawlessly now.

I would appreciate the feedback, whether the package installs on your machine.
