[opam-devel] adding OPAM pkg-config path to env

[Anil Madhavapeddy]

Do we have an open bug in OPAM about some mechanism to extend the environment exported by `opam config env`?

It would be really convenient if it also exported PKG_CONFIG_PATH to point to `opam config show prefix`/lib/pkgconfig, and it would be even nicer if this could be done without modifying OPAM for every new environment variable.
