#libxml2 ⇒ Object

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Some configure scripts won't find libxml2 without help. This is a no-op with macOS SDK 10.15.4 and later.
