# - Find the native PNG includes and library
#
# This module defines
# XPM_INCLUDE_DIR, where to find png.h, etc.
# XPM_LIBRARIES, the libraries to link against to use PNG.
# XPM_DEFINITIONS - You should ADD_DEFINITONS(${PNG_DEFINITIONS}) before compiling code that includes png library files.
# XPM_FOUND, If false, do not try to use PNG.
# also defined, but not for general use are
# XPM_LIBRARY, where to find the PNG library.
# None of the above will be defined unles zlib can be found.
# PNG depends on Zlib
