Chipmunk Physics

Using the tuitorial on this site I try to build a make file using cmake only to have this happen. How can I fix this?

blakat@blakat-desktop:~/Chipmunk-7.0.1$ cmake -D CMAKE_BUILD_TYPE=Debug .
Configuring Chipmunk2D version 7.0.1
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

Looks like you are using Linux of some flavor? Make sure you have GLEW and GLFW2 installed. That's what CMake is trying to tell you.
