I'm still fairly new to it.

Maybe the initial version - then you add logic to deal with different
versions of Xcode/Visual Studio etc, then some more logic to find
different packages that rust requires to build on a multitude of
systems etc. etc.

Sometimes you can get away writing something new and simple that just
deals with your use case (building Rust here). The problem is if you
end up with lots of feature creep re-discovering all the knowledge
that is encoded in existing tools - eg. the many modules for config
checks, locating packages etc. that come with CMake, automake, SCons

By all means, have a go at writing that initial version and see how
well it serves you - but be prepared to switch if it looks like you
are re-inventing something that already exists.
