From-scratch clone/build fails on `src/ftxui_sample/CMakeFiles/intro.dir/main.cpp.obj`

[sniggyfigbat]

Note: I also encountered this issue, but it already has an issue which includes a fix, so I've elided it here.

Running on Windows 10.

Configure/generate the clang Debug CMake preset.

• Using Ninja as the generator; not explicitly listed in README_building.md, but README_dependencies.md specifically shows it in the example command, so I assume it's supposed to work.
• Several warnings:

• I've changed no configuration options.
• I installed vcvarsall.bat with setup-cpp. It's not on PATH, possibly that's a problem?
• No idea what the test/constexpr_tests.cpp thing is about.

Run cmake --build ./out\build\windows-clang-debug.

• Not cmake --build ./build, which is what README_building.md currently says; that seems to be out of date with the CMake presets.
• Warning in fmt\base.h and src\format.cc.

• Failure on src/ftxui_sample/CMakeFiles/intro.dir/main.cpp.obj. No meaningful output given?

• Further warnings in spdlog. These don't look too bad.

So the problem looks like it might be specific to windows-clang (which is a tested platform) and the warnings seem to be coming from cppcheck (which is also tested), this is strange, as all of that is on the CI
