+From 04f776e73248d19d9beaf4ea8d407b7c85ecc9c9 Mon Sep 17 00:00:00 2001
+From: James Le Cuirot <chewi@gentoo.org>
+Date: Sun, 24 Feb 2019 20:25:34 +0000
+Subject: [PATCH] Allow use of external minizip library instead of linking just
+ zlib
+
+Some distributions package the minizip part of zlib, as well as zlib
+itself, so allow that to be used with help from pkg-config.
