...which is another argument for just not changing anything.  I mean,
again, the current Windows build system is unbeautiful and
occasionally takes some work, but if we switch to cmake, that has to
get enough better to make up for all of the things that get worse.
And it's far from obvious than this will be so, especially when you
consider the fact that many people have detailed knowledge of how to
tweak the current system to do what they want.  As you point out here,
a lot of that stuff may stop working if we replace the system
