Why can't I run the binary instead of cargo run --release?

[Tameflame]

Running cargo build --release then trying to run ./target/release/rust-background-removal gives the following error:

./target/release/rust-background-removal: error while loading shared libraries: libonnxruntime.so.1.16.0: cannot open shared object file: No such file or directory

I'm not sure why. I also notice that running cargo run --release causes additional libraries to compile before running, how does that happen? I don't see anything in the code that would do that
