# SYNOPSIS
#
# AX_LIB_MAPNIK([MINIMUM-VERSION])
#
# 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:
#
# no - do not check for mapnik library
#
# yes - do check for mapnik library in standard locations (xml2-config
# should be in the PATH)
#
# path - complete path to mapnik-config utility, use this option if mapnik-config
# can't be found in the PATH
#
# This macro calls:
#
# AC_SUBST(MAPNIK_CFLAGS)
# AC_SUBST(MAPNIK_LDFLAGS)
# AC_SUBST(MAPNIK_VERSION)
#
# And sets:
#
# HAVE_MAPNIK
