I am trying to create a node that will help me take an ROS Image and convert it to an OpenCV image. I am following the "Converting between ROS images and OpenCV images" tutorial. At step 9, I have created a cakin package with the required dependencies. When I paste the code given in the tutorial, and catkin_make, I get a ton of errors of style "... undefined reference to..." (this is a truncated example of my errors)

but I have checked and all of those included libraries exist in /usr/include, as well as other locations. What is the problem?
