Block building STL in wrong command prompt

[fsb4000]

Fixes #4639

I didn't test ARM command prompts.

Our test suite doesn't use CMake Presets. So manual testing is needed... CI runs CMake like this: https://github.com/microsoft/STL/blob/e36ee6c2b9bc6f5b1f70776c18cf5d3a93a69798/azure-devops/cmake-configure-build.yml#L32-L39

Can you also test building with the Visual Studio IDE?

[fsb4000]

Yes, it works.

It seems VS Studio also doesn't use CMake Presets directly. VS IDE might parse the CMake Presets but it runs cmake like this:

This doesn't match the presets. Without this patch, it does.

I believe that with this patch, Visual Studio sees all presets as disabled, because VS doesn't set $env{Platform}, and thus it falls back to the predefined configurations.

After looking into this deeper I'm not sure if it is even the right direction. People were complaining about tests not building in a wrong command prompt, not the STL itself. I'm not even sure that you can't build the STL itself this way.

[fsb4000]

@AlexGuteniev Yes, I know. But: 1) For tests, we need to modify stl-lit.py, not CMake. 2) You can build the wrong preset in the wrong command prompt; I tested it. How it works, for example: You are in an x64 command prompt and you build an x86 preset. It finishes without error. It creates the out/x86 folder, but the libs would be x64. Later, when you open an x86 command prompt and run tests from the out/x86 folder, you will get an error about a mismatch in architecture.

So I think my patch can help with these issues, partly. But we also can make a patch for stl-lit.py.

Thanks, this is awesome!! :heart_eyes_cat: I pushed a commit to simplify the logic with CMake's "inList" condition, see https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html#condition .

(They also support regex "matches", but (1) their regex syntax has weirdness and (2) while it would save a few lines in the JSON, it would look more complicated than the list of ["meow", ""], so I chose the simpler option.)

I re-verified enabled and disabled cases in the terminal, and that the VS IDE works (actually the first time I've built the STL in the IDE :joy_cat:).

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.

Thanks for this quality-of-life improvement for contributors! :magic_wand: :chart_with_upwards_trend: :heart_eyes_cat:
