I'm using Ubuntu 14.04.5 LTS and installed ROS Indigo.

Now, I'm trying to follow the steps on this link (http://wiki.ros.org/xv_11_laser_driver/Tutorials/Running%20the%20XV-11%20Node), but in Part "0.1 Startup the XV11 driver", it says that I must have "cwru-ros-pkg environment setup" in my terminal, but i don't have any clue for setup this cwru-ros-pkg in ROS Indigo.

Anyone have idea with this?
