Yes, the superbuild is currently only known to support Ninja on Windows.
Visual Studio is certainly out for various reasons, but NMake is
probably possible; patches would be welcome if NMake is required for
some reason. Some conditional should probably guard this section and not
do it for NMake:

but that may not be sufficient either.
