Installing freenect_stack from source

edit

I downloaded the source code for freenect_stack from git to the src folder of my catkin workspace. When I tried to build it using catkin_make, I got the following error:

*-- +++ processing catkin package: 'freenect_camera'
-- ==> add_subdirectory(freenect_stack/freenect_camera)
*CMake Error at /home/ubuntu/ros_catkin_ws/devel/share/catkin/cmake/catkinConfig.cmake:72 (find_package):

What is the camera_info_make config file? And how do I get it?
