Some Rust libraries can be built with cargo tool into a C library with dll+lib files. For example, resvg. It would be great to enable vcpkg to build such libraries.

For example: to compile resvg C binding:

1. Download and run rustup-init.exe from https://www.rust-lang.org/tools/install
2. Compile resvg:

git clone https://github.com/RazrFalcon/resvg.git
cd resvg\c-api
%USERPROFILE%\.cargo\bin\cargo build --release

This creates resvg.dll and resvg.dll.lib.

Proposed solution
Add cargo as build tool.
