Yet more issues surfacing with CMake 3.20.  Are these regressions being reported back to Kitware somewhere?

My bad. Upgraded Visual Studio and it now ships with cmake 3.20.

choco installing cmake 3.19 fixed the errors.

Original working system:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community>cl
Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29912 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community>cmake --version
cmake version 3.19.20122902-MSVC_2

--------------------

New system (bad cmake):

W:\Development\wsbuild>cl
Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30037 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

W:\Development\wsbuild>cmake --version
cmake version 3.20.21032501-MSVC_2

Fixed with:

choco install -y cmake --version 3.19.8

update PATH to reach this cmake first

W:\Development\wsbuild64>where cmake
C:\Program Files\CMake\bin\cmake.exe
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe

Is it a matter of tweaking the build to allow the warning to pass or does this require a code change?
