-Subject: [PATCH] Use pkg-config to find freetype
+From 3eec911197081a63d9dae28f1784ad01a06fb60a Mon Sep 17 00:00:00 2001
+From: Colin Watson <cjwatson@ubuntu.com>
+Date: Tue, 30 Jan 2018 21:54:17 +0000
+Subject: build: Use pkg-config to find FreeType
 
-As of freetype-2.9.1 the freetype-config script has been deprecated and
-is no longer shipped by default.
+pkg-config is apparently preferred over freetype-config these days (see
+the BUGS section of freetype-config(1)).  pkg-config support was added
+to FreeType in version 2.1.5, which was released in 2003, so it should
+comfortably be available everywhere by now.
 
-Based on a patch by Lars Wendler <polynomial-c@gentoo.org>.
+We no longer need to explicitly substitute FREETYPE_CFLAGS and
+FREETYPE_LIBS, since PKG_CHECK_MODULES does that automatically.
+
+Fixes Debian bug #887721.
