From b68e1c3a40aa116f0c6236114be79bd79f472258 Mon Sep 17 00:00:00 2001
From: James Le Cuirot <chewi@gentoo.org>
Date: Fri, 17 Oct 2025 22:08:50 +0100
Subject: [PATCH] cmake: Determine installation paths dynamically
Use pkg-config data, then systemd-path, then respect GNUInstallDirs.
CMAKE_INSTALL_LIBDIR is not used because that is the
architecture-specific directory (e.g. lib64).
