+path. From there, launch an MSYS2 shell via e.g.
+`\msys64\msys2_shell.cmd -full-path -mingw64` (preserving the earlier
+environment, allowing the MSVC headers/libraries and clang-cl to be found).

Actually, it does work with a python installed to a path that doesn't contain spaces (e.g. `C:\Users\Administrator\AppData\Local\Programs\Python\Python39` works, but `C:\Program Files\Python..` doesn't).
I'll try to mention both approaches in the doc.
