Note: the functionality of this module is governed by Meson's rules on mixing build systems.
The pkgconfig module now generates uninstalled pc files as well. For any generated foo.pc file, an extra foo-uninstalled.pc file is placed into <builddir>/meson-uninstalled. They can be used to build applications against libraries built by meson without installing them, by pointing PKG_CONFIG_PATH to that directory. This is an experimental feature provided on a best-effort basis, it might not work in all use-cases.
