Cannot load message class for []. Are your messages built?

edit

I have a node that subscribes to /joy topic, converts to /cmd_vel topic, and publishes to arduino via rosserial. I am receiving joy messages just fine, but when I

rosmsg show control/Velocity

(control is the name of the node, Velocity is the message), it says:

Unable to load msg [control/Velocity]: Cannot locate message [Velocity]: unknown package [control] on search path.

When I rostopic echo /cmd_vel, I get

Error: Cannot load message class for [control/Velocity]. Are your messages build?

I have tried many things. I believe that my environment variables are good, and I tried going into the root of my workspace, catkin_make clean, catkin_make, and source my devel/setup.sh file. Still, nothing seems to be working. My Velocity.msg file is in my CmakeLists.txt and the required build depends and run time depends are in my package.xml (build depend message_generation and run depend message_runtime).

Any advice would be helpful. Thanks!
