Allow override PKG_CONFIG_PATH via env, making it possible to easily inject alternative library builds for testing or bisecting. This was only possible when the premake script didn't override it which it unconditionally did on macos. Also don't expose the variable holding the path directly but offer a function to append to the path instead. Ref: #8135 Signed-off-by: Ralph Sennhauser <ralph.sennhauser@gmail.com>
