| ## Purpose: |
| ## This class is to support building with cargo. It |
| ## must be different than cargo.bbclass because Rust |
| ## now builds with Cargo but cannot use cargo.bbclass |
| ## due to dependencies and assumptions in cargo.bbclass |
| ## that Rust & Cargo are already installed. So this |
| ## is used by cargo.bbclass and Rust |

| # cross compiling unless this is defined. We set up pkg-config appropriately |
