[PATCH] D77740: [CMake] Add a warning message to prepare the upcoming upgrade to CMake 3.13.4

[Louis Dionne via Phabricator via llvm-commits]

Honestly, I would either upgrade once soon, or upgrade once later after we branch for 11.0.0 (as we agreed on the list). Doing two CMake upgrades back-to-back doesn't sound fun or like a good use of everybody's time.
