If you don't have VS code with C++ build tools, or just the C++ build tools installed, you can use the MINGW compiler:

scoop install mingw
rustup toolchain install stable-x86_64-pc-windows-gnu
rustup default stable-x86_64-pc-windows-gnu

It might be necessary to set up an env var (to be tested): $env:CARGO_BUILD_TARGET = "x86_64-pc-windows-gnu"
