#  Try to find the Freenect library to read from Kinect
#
#  You must provide a FREENECT_ROOT_DIR which contains lib and include directories
#
#  Once done this will define
#
#  FREENECT_FOUND - system found Freenect
#  FREENECT_INCLUDE_DIRS - the Freenect include directory
#  FREENECT_LIBRARIES - Link this to use Freenect
