I have not used Rust very much. But in https://doc.rust-lang.org/cargo/reference/build-scripts.html https://doc.rust-lang.org/cargo/reference/build-scripts.html I find comments like, It is recommended to carefully consider each dependency you add, weighing against the impact on compile time, licensing, maintenance, etc. Cargo will attempt to reuse a dependency if it is shared between build dependencies and normal dependencies. However, this is not always possible, for example when cross-compiling, so keep that in consideration of the impact on compile time. So it looks like cargo can have the same issue that make does with recursive dependencies.
