But! This is just the bridge. The tool of course has a native build system (i.e. construct and execute a build graph). It's not feasible to start by rewriting every library's build system, so we start like this.That being said, I'll have a go at sel4 with the native build system. I use it for all my C projects already. Nothing tastes better than dog food, after all!
