As an additional comment, I don't see us accepting a build system
that doesn't run on pretty old cmakes.  We have never had a policy
of "latest and greatest is required" for *any* build support tool,
and cmake isn't likely to be given an exception.

BTW, I just noticed that cmake doesn't seem to be supplied as part of
Apple's dev tools, at least not up to current (El Capitan) releases.
That's going to be a rather large minus to be taken into account
whenever we make the go/no-go decision on this.
