# - Find JPEGTURBO
# Find the libjpeg-turbo includes and library
# This module defines
#  JPEGTURBO_INCLUDE_DIR, where to find jpeglib.h and turbojpeg.h, etc.
#  JPEGTURBO_LIBRARIES, the libraries needed to use libjpeg-turbo.
#  JPEGTURBO_FOUND, If false, do not try to use libjpeg-turbo.
# also defined, but not for general use are
#  JPEGTURBO_LIBRARY, where to find the libjpeg-turbo library.
