[idea] Deprecation of RESTINIO_FIND_DEPS in favor of RESTINIO_EXTERNAL_FMT, RESTINIO_EXTERNAL_CATCH2 and so on
Dependency management in CMake scripts started from very simple things but evolved to rather complex scheme that I don't understand fully. Now we have RESTINIO_FIND_DEPS with additional case RESTINIO_USE_EXTERNAL_HTTP_PARSER (and I don't get an idea of RESTINIO_FIND_DEPS=ON and RESTINIO_USE_EXTERNAL_HTTP_PARSER=OFF case) plus RESTINIO_USE_EXTERNAL_*_LITE options.
Maybe it's better to remove RESTINIO_FIND_DEPS and use new options like RESTINIO_USE_EXTERNAL_FMT, RESTINIO_USE_EXTERNAL_HTTP_PARSER (+RESTINIO_USE_EXTERNAL_UNOFFICIAL_HTTP_PARSER), RESTINIO_USE_EXTERNAL_CATCH2 and other.
I think that change should lead to change a version number, e.g. 0.7.0 instead of 0.6.15. And that version change can be done during adopting to Catch2 v3.
v3 of Catch2 is no more single-header header-only library and switching to v3 may require some refactoring of RESTinio's test. It's a significant change to be reflected in RESTinio's version bump.
