Thanks this step passed, but now I face with another error in dependencies. 

```

```

indeed, this library is python and internally it's using a rust library. the 
`cpython` is one its dependencies that I packaged it (`rust-cpython`) and it 
needs to it. I don't know how can I add rust  dependencies here since I'm using 
python build system. I added it to inputs but not resolved.

Indeed now the problem is adding dependencies (some of them rust and some of 
them python) to this package while I'm using the python build system. Do you 
have any idea?
