While I agree it would make more sense to have Clara as a separate
dependency of Catch2, from our chat it's clear Phil feels strongly
about having a private copy and the reasons he gives do make sense
(essentially, making sure Catch2 uses a known-compatible version
of Clara while not forcing the users to use the same version).

Since they are doing all the work of making sure that such a
"private Clara" does not conflict with "user Clara", I think we
should respect their wishes and just bundle it.

Hm, that sounds surprising (or perhaps my email was confusing): I think
the Python script is required to generate single_include/catch.hpp from
all the headers in include/. Our (new) plan, however, is to ignore
single_include/ entirely and always use include/, including installing
the multi-header variant.

Ok, let me take a quick stab at it to at least get one test building.
Will ping you when push.
