It seems like a lot, but it takes only 10 minutes to set up.  Follow these
steps and you'll have a working build environment on Windows, at least
until something changes.  As they say, "Give a man a fish, and you feed him
for a day.  Teach a man to fish, and he'll keep asking you how to do things
for a lifetime".
