Description

When trying to build a git dependency that is inside a workspace, cargo can take into account the root of the workspace for versions. The generator doesnt take that into account.

This doesn't seem to work with cargo vendor either; since the sources generator aims to replicate Cargo's native vendoring mechanism, I'm not sure if there is a way we can make this work.

You can test if vendoring is possible for your project like this:
(run these in a clean source tree of the project)

mkdir .cargo
cargo vendor --locked --versioned-dirs > .cargo/config
cargo build --offline

Overall, this looks like the same issue as rust-lang/cargo#11192
