The added complexity is not trivial, but need not be large, and most importantly, is borne by us, not all other users, packagers, systems administrators, etc. Plus, having done so, we'll be in control of what features are available to us, which will provide an offsetting increase in our productivity. Regarding the other dependencies you mentioned, they're mostly providing standardized interfaces (libc, C++11, etc.), except for Python. But Python has lots of optional external dependencies (ncurses, etc.) and would not be a good candidate for shipping inline, plus it's large. CMake's external dependencies are very minimal, and it's not particularly large, making it a much better candidate for bundling.

Ok, I'm out of arguments for this one, but I still don't think we
should. :) If everyone else feels strongly about this route, I don't
mind.

cheers,
