like blas and lapack.

Inspiration taken from `makeDesktopItem`.

# Example usage in a derivation:
#
# { …, makePkgconfigItem, copyPkgconfigItems, … }:
#
# let pkgconfigItem = makePkgconfigItem { … }; in
# stdenv.mkDerivation {
# …
# nativeBuildInputs = [ copyPkgconfigItems ];
#
# pkgconfigItems = [ pkgconfigItem ];
# …

#
# This hook will copy files which are either given by full path
# or all '*.pc' files placed inside the 'lib/pkgconfig'
# folder of each `pkgconfigItems` argument.
