4Subject: [PATCH] cmake: support absolute paths for install dirs in pkg-config
5
6The GNUInstallDirs module supports absolute paths for CMAKE_INSTALL_LIBDIR and CMAKE_INSTALL_INCLUDEDIR. Some package managers like Nix depend on this behaviour. See https://github.com/NixOS/nixpkgs/issues/144170 for the nixpkgs tracking issue.
