#  Try to find the Sixense controller library
#
#  You must provide a SIXENSE_ROOT_DIR which contains lib and include directories
#
#  Once done this will define
#
#  SIXENSE_FOUND - system found Sixense
#  SIXENSE_INCLUDE_DIRS - the Sixense include directory
#  SIXENSE_LIBRARIES - Link this to use Sixense
