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

W:\Development\wsbuild64>
W:\Development\wsbuild64>cmake --version
cmake version 3.19.8

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