# - Find UUID
# Find the native UUID includes and library
# This module defines
#  UUID_INCLUDE_DIR, where to find jpeglib.h, etc.
#  UUID_LIBRARIES, the libraries needed to use UUID.
#  UUID_FOUND, If false, do not try to use UUID.
# also defined, but not for general use are
#  UUID_LIBRARY, where to find the UUID library.
