0001 # - Try to find the PoDoFo library
0002 #
0003 # Windows users MUST set when building:
0004 #
0005 # PoDoFo_USE_SHARED - whether use PoDoFo as shared library
0006 #
0007 # Once done this will define:
0008 #
0009 # PoDoFo_FOUND - system has the PoDoFo library
0010 # PoDoFo_INCLUDE_DIRS - the PoDoFo include directory
0011 # PoDoFo_LIBRARIES - the libraries needed to use PoDoFo
0012 # PoDoFo_DEFINITIONS - the definitions needed to use PoDoFo
