Maybe if you explain what you are expecting to happen? If you set
PKG_CONFIG_PATH in your environment then pkg-config will add that
directory the list of places it searches for .pc files for other
packages. However it will have no affect on your current package,
leacing you (correctly) in complete control of how to configure the
thing you are building.

So, again, what effect are you trying to achieve here?
