add option to point to pre-built target location for when build is not in current directory

[aaronenberg]

I'd really love if cargo-deb supported this workflow:

cargo build --release --target-dir ~/foo
cargo deb --no-build --target-dir ~/foo

Any problems with this?

[aaronenberg]

I see that cargo-deb respects CARGO_TARGET_DIR. So I can set CARGO_TARGET_DIR=~/foo to get my desired behavior.
Still it would be nice to have it as a command-line option.

The env var probably works by being picked by cargo metadata. I'm not sure if it's worth complexity to support it also as an argument. You're the first person I've seen who uses the command-line arg instead of the env var.

That's fair. I'll probably start using the env var too. Thanks for considering
