Robot test framework for Rust

I need to generate unit-test and integration-test reports (cargo test command) of a Rust project. To do this I am using RobotFramework. When I try to run cargo test command it fails with an error /usr/bin/ld: cannot find -lpython3.12: No such file or directory.

Cargo.toml

pyproject.toml

If I build the Rust library using maturin develop, it builds successfully with the below output
