It seems like the codegen in build.rs is not being run, but I have no idea why that would be. Could this be related? rust-lang/cargo#4468

    println!("cargo:rerun-if-env-changed=FORCE_REBUILD");

it looks like you can set the FORCE_REBUILD env var as a work around

A ran cargo clean and this resolved the issue
