# SYNOPSIS
#
# AX_LIB_MAPNIK([MINIMUM-VERSION])
# AX_LIB_MAPNIK()
#
# DESCRIPTION
#
# This macro provides tests of availability of mapnik 'libmapnik' library
# of particular version or newer.
#
# AX_LIB_MAPNIK macro takes only one argument which is optional. If
# there is no required version passed, then macro does not run version
# test.
#
#
# The --with-mapnik option takes one of three possible values:
