You updated bootstrapping. Will you update the requirements in ports.cmake to make people upgrade vcpkg-tool before updating cmake?

vcpkg/scripts/ports.cmake

Lines 28 to 29 in 111220b

	include("${SCRIPTS}/cmake/vcpkg_minimum_required.cmake")
	vcpkg_minimum_required(VERSION 2021-05-05)

We intentionally don’t update that unless we have a specific reason to force a rebootstrap; the cmake version update seems a good reason to me so maybe it should go in that review? I can prepare a stand-alone update PR if you wish

I made a comment in #18955 now.

It might be forced for CMAKE_VERSION VERSION_GREATER 3.21 to limit scope, but OTOH this might not be desired from a maintenance point of view.

That's already always true because the vcpkg binary will already download 3.21 if the one on the system is older than the one it has configured.
