@gerard-ryan-immersaview I still can't reproduce the problem after following your tips, am I going about it the wrong way? Are you able to give some advice? |
And you configured the kit to be unspecified?
I noticed that you use the CMake version that comes with Visual Studio and not the direct one too. |

@gcampbell-msft @gerard-ryan-immersaview Following the steps given by the user, this issue we can reproduce on top of the latest VSCode and you can get some information below: ENV: Repro steps recording: |

Additional Information
If I truly let CMake decide by running it on the CLI it finds the Compiler and environment I'd expect it to use.
