I see, what is missing are the "extras" like catch_discover_tests, but
it seems they can just be copied to lib/cmake/Catch2.

To build clingo with 3.3.2, the find_package(Catch2 3.1 ...) command
just needed to be adjusted, but I went ahead and unbundled the remaining
dependencies as well. Should this be a separate issue?
For catch2, it seems simpler to me to build it with CMake, as I don't
see the use case for the static library (as a second output). If you
prefer, I can change it back to Meson though and just copy the files
from the extras directory as well (provided it works).
