OK, I'm a little confused.  The page that explains how to generate
this json file doesn't mention anything about generators or -G.

Are the directions on the page simply assuming somethign that isn't true
in this case?

I don't need to actually change the way I'm building the code -- I
still want VS projects for building the code.  I just need to create
this JSON file.

As I understand it, this JSON file feeds clang all the necessary
include search paths and relevant preprocessor symbol definitions in
order to properly interpret the source code in a particular
compilation context.
