I would check "catch2" before "catch" as newer versions use "catch2".

Could be seen weird to include config.h in an header but
as is limited to test director I don't find it an issue.

Could be an option to have

#if !defined(HAVE_CATCH2_CATCH_HPP) && !defined(HAVE_CATCH_CATCH_HPP)
#include <config.h>
#endif

so you can avoid to include from module and header.
