#mkmf_config(pkg: nil, dir: nil, static: nil) ⇒ Object

pkg: the pkg-config file name (without the .pc extension) dir: inject the directory path for the pkg-config file (probably only useful for tests) static: the name of the static library archive (without the “lib” prefix or the file extension), or nil for dynamic linking

we might be able to be terribly clever and infer the name of the static archive file, but unfortunately projects have so much freedom in what they can report (for name, for libs, etc.) that it feels unreliable to try to do so, so I’m preferring to just have the developer make it explicit.
