Minor updates: (#36)

* Eigen example CMake target name changed from eigen to eigen_space_type.
** The name seems to collide with the eigen library target name since v3.4.
** Similarly updated the opencv example target name.
* CMake package installation directory updated.
* Repaired broken reference links in the README.md.
