I’m not sure. I believe it’s because other applications use
imagemagick 7, and they don’t want to cause issues by putting both on
PATH or something. OTOH I don’t think that matters too much with
pkg-config because it can detect versions, but I don’t really know.

There’s a similar issue with makeinfo, which is why we’re detecting
homebrew already.
