Do you mean it's not found even when present? Perhaps just comment it
out, with a "TODO" or "XXX" explaining what this would add, but the
build system needs some changes to pick it up correctly.

I think most packagers knows what pkg-config is for, so the explanation
seems unnecessary. Are you sure it's only used for network-manager? I
feel bad for complaining about *too many* comments however :)

Is this related to the docbook-xml comment in native-inputs? Does this
make it work? I would prefer to have the comment here in that case. E.g.
"This is necessary to find schemas from docbook-xml" or similar.

Is this variable common in the various KDE build phases? If it's
explained somewhere else, it's probably not necessary to add the same
comment (as I requested in the previous patch) to all of them.

Otherwise LGTM!
