How install dev packege for protobuf?

I install package nixos.protobuf3_11 and protoc is available in my environment. But dev lib for C++ isn’t avaible, for example my cmake output:

CMake Error at /nix/store/3rvfqxl4rlikdzli25hqb2fah3wnw91l-cmake-3.16.3/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):

How install dev version of protobuf?

Don’t install libraries through nix-env or systemPackages, use nix-shell instead. See FAQ/I installed a library but my compiler is not finding it. Why? - NixOS Wiki for details

Using of nix-shell don’t help me. I used the next script for run nix-shell enviroment:

{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
    buildInputs = with pkgs; [
        # other geant4 data ...


Its allow use geant4 framework, but don’t present protobuf.

try to add pkg-config in buildInputs.

No it doesn’t help. In this project I load GEANT4 cpp-framework as cmake module and for its cmake finds headers and libraries, another libraries also connect. Probability, the problem is the lack of dev-files in the package protobuf3_11.
