Re: [PATCH] Makefile: fix parallel build race

The idea to extend the CMake to more than just Windows is contrary to what Junio said in https://lore.kernel.org/git/xmqq1rmcm6md.fsf@gitster.c.googlers.com/:

If that is not enough to tone down opposing opinions (the opinion of the Git maintainer is more important, after all, it's his maintenance burden so he gets to decide), you can also look at this statement from https://lore.kernel.org/git/xmqq8sikblv2.fsf@gitster.c.googlers.com/:

The only reason we have CMake in addition to the Makefile (and the autoconf-based) setup is that CMake makes it possible to build Git on Windows in the development environment with which the majority of the developers on Windows are familiar: Visual Studio.

If it weren't for those developers, for who it would be a ridiculous suggestion to "just go download GNU make", we would not have the CMake based build at all.

And I am still agreeing with what Junio further said in the second mail I linked above:

	[...] it is unclear why it would be beneficial to slow our
	existing developers down by forcing them to become familiar with
	CMake.

So now we are discussing to extend the CMake build to allow Linux and macOS developers to use it, to, for little to no benefit. We are very much in the situation where we are slowed down by discussing something as non-essential as extending our CMake support beyond Windows, while patches that are provably much more beneficial to a lot more people are left under-reviewed.

Even worse: reviewers who _could_ provide high-quality reviews for those patches (which takes a lot of time and diligence), but are as much pressed for time as I am and therefore have to choose wisely how to spend their time, are _actively_ distracted from spending their time more wisely.

Can't we please focus on more relevant things again? Pretty please?

Ciao, Johannes
