#  Try to find the Skeltrack library to perform skeleton tracking via depth camera
#
#  You must provide a SKELTRACK_ROOT_DIR which contains lib and include directories
#
#  Once done this will define
#
#  SKELTRACK_FOUND - system found Skeltrack
#  SKELTRACK_INCLUDE_DIRS - the Skeltrack include directory
#  SKELTRACK_LIBRARIES - Link this to use Skeltrack
