Allow dpkg-shlibdeps flags or Debian rules file about cargo-deb

[kornelski]

If I understand correctly, the rules file is for dh build, and it's typically a makefile. I don't see how that would be used for Cargo builds. Cargo-deb doesn't use dh, and it's more rooted in the side of Rust/Cargo, than Debian's packaging tooling.

If you're familiar with Debian's package tooling, maybe debcargo would work better?

Ideally I'd love cargo deb work automagically out of the box, without extra flags or config. Does your library2.so contain references to /usr/lib/my-libraries that something like ldd could read? It'd be cool if the path could be auto-detected.

Or maybe you're setting LD_LIBRARY_PATH that I could forward to dpkg-shlibdeps?
