This only applies if you are using system libraries. Most libraries do not rely on external dependencies. Regardless, cargo is build tool for Rust, not a replacement for your distribution's package manager. If you want to build a library that's fully static then use the musl target and build your external dependencies with musl. If you want distribution integration then use a makefile or other tool.
