friendly error message when missing pcsc-lite-devel

[ktdreyer]

I was building pysequoia recently on Fedora. I found that nettle-sys prints a friendly error message when nettle-devel is not installed:

  Building nettle-sys failed.
  Because: 
  pkg-config exited with status code 1
  > PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags nettle

  The system library `nettle` required by crate `nettle-sys` was not found.
  The file `nettle.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `nettle.pc`.


  Please make sure the necessary build dependencies are installed.

  If you are using Debian (or a derivative), try:

      $ sudo apt install clang llvm pkg-config nettle-dev

  If you are using Arch (or a derivative), try:

      $ sudo pacman -S clang pkg-config nettle --needed

  If you are using Fedora (or a derivative), try:

      $ sudo dnf install clang pkg-config nettle-devel

  See https://gitlab.com/sequoia-pgp/nettle-sys#building for more information.

  Error: "Building nettle-sys failed."
warning: build failed, waiting for other jobs to finish...

Could we do something like that for this project when pcsc-lite-devel is missing?

(I originally reported this at wiktor-k/pysequoia#26 and the maintainer directed me here)
