Unknown CMake command "add_action_files"

edit

Ubuntu 14.04, ROS Indigo.

I've been following along with the tutorial at: http://wiki.ros.org/ROS/Tutorials/Cre... and when I get to the portion where it instructs me to run catkin_make install I get:

I'm fairly new to ROS and CMake so I'm completely stumped. I've made sure to source both /opt/ros/indigo/setup.bash and ~/catkin_ws/devel/setup.bash.

Any ideas what could be causing this?
