This module defines the following variables:

``PODOFO_FOUND``
  True if PODOFO found.

``PODOFO_INCLUDE_DIRS``
  where to find podofo/POFDoc.h, etc.

``PODOFO_LIBRARIES``
  List of podofo libraries to link.

``PODOFO_VERSION_STRING``
  Version of podofo library defined in podofo/base/podofo_config.h
