system library was not found after installing with sudo apt-get install -y

I did sudo apt-get update && sudo apt-get install -y libnftnl-dev pkg-config but cargo test still fails with

  --- stderr
  thread 'main' panicked at nftnl-sys/build.rs:44:14:
  called `Result::unwrap()` on an `Err` value: 
  pkg-config exited with status code 1
  > PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/ PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags libnftnl libnftnl >= 1.0.6

  The system library `libnftnl` required by crate `nftnl-sys` was not found.
  The file `libnftnl.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  PKG_CONFIG_PATH contains the following:
      - /usr/lib/x86_64-linux-gnu/pkgconfig/

  HINT: you may need to install a package such as libnftnl, libnftnl-dev or libnftnl-devel.

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
