# - Find the native FriBiDI includes and library
#
#
# This module defines
#  FRIBIDI_INCLUDE_DIR, where to find fribidi.h, etc.
#  FRIBIDI_LIBRARIES, the libraries to link against to use FriBiDi.
#  PNG_DEFINITIONS - You should ADD_DEFINITONS(${PNG_DEFINITIONS}) before compiling code that includes png library files.
#  FRIBIDI_FOUND, If false, do not try to use PNG.
# also defined, but not for general use are
#  FRIBIDI_LIBRARY, where to find the FriBiDi library.
