I think this "simplistic Bash script" is called "configure" and is
generated by autoconf from our  I don't think the word
"simplistic" describes it very well (nor does "maintainable").

I don't think we're interested in maintaining more build systems than we
already are.  If cmake can replace the current MSVC tooling and
autoconf, all in one, my impression is that we're in.  If we're
replacing two tools we've hammered pretty well over the years with two
tools that we haven't, I doubt we're interested.
