+From bb925f636a8a3f662ef2a5f2826a7e0138dba266 Mon Sep 17 00:00:00 2001
+From: Raphael Kubo da Costa <rakuco@FreeBSD.org>
+Date: Wed, 31 Dec 2014 01:15:28 +0200
+Subject: [PATCH] Rename INSTALL_PREFIX to KADU_INSTALL_PREFIX.
+
+In CMake 3.1.0, INSTALL_PREFIX is now an optional argument to
+configure_package_config_file(), so our call was confusing the
+function's argument parsing code.
+
+Fix it by renaming INSTALL_PREFIX to KADU_INSTALL_PREFIX.
