I sent a mail to the address in the README; let's wait for a reply.

Correction to myself: I now see that we only need to edit those source
files because we remove the bundled ones, but that's an argument
towards keeping that within the snippet imho.

Joke's on you, catch2 ships with both CMake's config stuff *and* pkg-
config.  Vendoring it is next to pointless (that is, unless you regard
sneaking it onto ancient Debian as the point).  Doctest also comes with
the usual CMake blurb.
