It won't require any hand-configuration. There is an easy way to
automate the configuration process by giving CMake a pre-populated
list of cache entries that drive the configuration.

Sure. As you've noted, that's a little harder if we're downloading
binaries on-the-fly as part of the installation. Right now, it's easy
to do this because the installers are standalone executables.
(Unfortunately, they're also *large* executables, and most users only
need part of what's in there).

This last bit is a little tricky, because we will be dependent on NSIS
to do the actual downloads. I don't know how robust it is, but any
fixes would have to go into NSIS itself.
