Build gdal with xercesc support for GML files

[mbarchfe@…]

If you call ogrinfo --formats it will list GML, but if you actually try to access a GML file, you will be surprised with the following error message:

ERROR 1: Unable to create Xerces C++ based GML reader, Xerces support
not configured into GDAL/OGR.

With the following simple variant GML files could be read:

variant xerces {
	depends_lib-append		port:xercesc
	configure.args-append	--with-xerces=${prefix}
}

Portfile patch

[mbarchfe@…]

Added the Portfile patch. Maybe the variant should be called gml instead of xerces.

Replying to ryandesign@…:

Fixed in ticket Ticket #18418

I left the variant name as xerces because that's the port library for which it adds support. Theoretically, GML support could be added through another XML parser.

[macsforever2000@…]

Added in r46597.
