I've installed visual rust 0.1.2, I have rustc.exe and some other files installed here: C:\Users\steve.cargo\bin
But when I try to build rust project in msvc 2015 I get this error:

C:\Program Files (x86)\MSBuild\VisualRust\VisualRust.Rust.targets(53,5): error : No Rust installation detected. You can download official Rust installer from https://www.rust-lang.org/downloads.html

How is the installation detected? How can I fix this?
