Compiling and installing k4w library: Follow the instructions on http://openkinect.org/wiki/Getting_Started for Ubuntu.

Go to build directory and type "cmake ..".
"make".
"sudo make install".
To uninstall, "sudo make uninstall".

In ROS, install the freenect-stack. Replace all the libfreenect library (.so) and binary files in the opt/ros/hydro directory with the ones we just compiled.

ROS libfreenect-stack should now work with kinect for windows.
