Including Cargo Input that's Pulled in By Git in .toml File

[Jaft]

I packaged up a Crate that's being pulled in by another package with Git but 
=cargo-build-system= keeps trying to pull it from GitHub (which, naturally, it 
can't do).

Is there something else I need to do beyond including it via the 
~#:cargo-inputs~ =argument=?

Alternatively, if there a way to get the =cargo-build-system= to not include 
it? It's marked as ~optional~ in the =Cargo.toml= file but =cargo-build-system= 
keeps trying to fetch it.

Thanks!
