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