Message : Pass through absolute paths to cmake config directly The previous code concatenates includedir to _harfbuzz_prefix verbatim, which results in a wrong final include path in case includedir is an absolute path. Instead, we can let meson determine the absolute include and lib paths in advance and save them in the cmake config. This is an issue in nixpkgs, where includedir is set to the final (absolute) path of the built library in the Nix store, which causes CMake projects depending on harfbuzz to not configure. See https://github.com/NixOS/nixpkgs/issues/180054.
