The Rust Compiler needs to find
rc.exefrom the Windows SDK, which it does by finding the linker, then searching through thePATHenv var to see ifrc.exeexists anywhere there:https://github.com/rust-lang/rust/blob/364da5d88d772fa40fb20353443595385443ac25/compiler/rustc_windows_rc/src/lib.rs#L141-L158
Instead, we can have
find-msvc-toolssearch the Windows SDK paths for tools if that tool is not found in the VC path.
