# - Try to find the LibOVR library to use the Oculus
#
#  You must provide a LIBOVR_ROOT_DIR which contains Lib and Include directories
#
#  Once done this will define
#
#  LIBOVR_FOUND - system found LibOVR
#  LIBOVR_INCLUDE_DIRS - the LibOVR include directory
#  LIBOVR_LIBRARIES - Link this to use LibOVR
