How do I select among the options /std:c++23preview and /std:c++latest in Visual Studio. I currently have:

```auto
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_EXTENSIONS OFF)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

```

and this results in “/std:c++latest” in my generated project (both in Visual Studio 2022, and in 2026). I have not been able to get " /std:c++23preview" via setting variables like above in CMake. I guess it should be possible, but I haven’t succeeded yet.

I have tried with CMake 4.2.1 and setting cmake\_minimum\_required(VERSION 4.2) too, suspecting that it should have an effect too.

Have I missed some obvious detail?

This was previously implemented and then reverted for reasons discussed in [CMake Issue 26692](https://gitlab.kitware.com/cmake/cmake/-/issues/26692#note_1635924).
