-In the latter case, I encourage you to download Interface99 as a [Git submodule] to be able to update it with `git submodule update --remote` when necessary. Also, note that by default, Interface99's `CMakeLists.txt` downloads Metalang99 [v1.13.0](https://github.com/Hirrolot/metalang99/releases/tag/v1.13.0) from the GitHub release archives; if you want to override this behaviour, you can do so by invoking [`FetchContent_Declare`] earlier.
