kalibr dependencies are not mapped to ROS packages

[luisrayas3]

Running rosdep install ... with the kalibr repo cloned into the workspace results in the error shown below. It seems like cloning the eigen_catkin repo would resolve a good chunk of them (and perhaps should be added to the instructions) but I'm not sure about the rest.
