Not all dependencies are listed in installation instruction.

README says:

$ sudo apt install libudev-dev
$ cargo install solana-foundation-delegation-program-cli

But for my Ubuntu 20.04 it was necessary to install some other packages:
apt install build-essential libudev-dev pkg-config libssl-dev -y

Without it there were errors during cargo's installation, like this:

error: failed to run custom build command for `hidapi v1.2.6`

Caused by:
  process didn't exit successfully: `/tmp/cargo-installZevy2N/release/build/hidapi-4e8337fb40e827d6/build-script-build` (exit code: 101)
