From the discussion in #20511, the comments in, and my experience spinning up in gRPC C++, I think the C++ instructions are missing the grpc_extra_deps() call. 

Figured I'd just spin up a quick PR, rather than file an issue. Feel free to do whatever you'd like to the change, ofc. 
Thanks! :)

gRPC C++

This directory contains the C++ implementation of gRPC.

To start using gRPC C++

This section describes how to add gRPC as a dependency to your C++ project.

In the C++ world, there's no universally accepted standard for managing project dependencies. Therefore, gRPC supports several major build systems, which should satisfy most users.


Bazel is the primary build system used by the core gRPC development team. Bazel provides fast builds and it easily handles dependencies that support bazel.

To add gRPC as a dependency in bazel:

  1. determine commit SHA for the grpc release you want to use
  2. Use the http_archive bazel rule to include gRPC source
    name = "com_github_grpc_grpc",
    urls = [
    strip_prefix = "grpc-YOUR_GRPC_COMMIT_SHA",
load("@com_github_grpc_grpc//bazel:grpc_deps.bzl", "grpc_deps")
load("@com_github_grpc_grpc//bazel:grpc_extra_deps.bzl", "grpc_extra_deps")


cmake is your best option if you cannot use bazel. It supports building on Linux, MacOS and Windows (official support) but also has a good chance of working on other platforms (no promises!). cmake has good support for crosscompiling and can be used for targeting the Android platform.

To build gRPC C++ from source, follow the BUILDING guide.


The canonical way to discover dependencies in CMake is the find_package command.

find_package(gRPC CONFIG REQUIRED)
target_link_libraries(my_exe gRPC::grpc++)

Full example

find_package can only find software that has already been installed on your system. In practice that means you'll need to install gRPC using cmake first. gRPC's cmake support provides the option to install gRPC either system-wide (not recommended) or under a directory prefix in a way that you can later easily use it with the find_package(gRPC CONFIG REQUIRED) command.

The following sections describe strategies to automatically build gRPC as part of your project.


If you are using CMake v3.11 or newer you should use CMake's FetchContent module. The first time you run CMake in a given build directory, FetchContent will clone the gRPC repository and its submodules. FetchContent_MakeAvailable() also sets up an add_subdirectory() rule for you. This causes gRPC to be built as part of your project.

cmake_minimum_required(VERSION 3.15)

  GIT_TAG        RELEASE_TAG_HERE  # e.g v1.28.0

target_link_libraries(my_exe grpc++)

Note that you need to install the prerequisites before building gRPC.

git submodule

If you cannot use FetchContent, another approach is to add the gRPC source tree to your project as a git submodule. You can then add it to your CMake project with add_subdirectory(). Example

Support system-installed gRPC

If your project builds gRPC you should still consider the case where a user wants to build your software using a previously installed gRPC. Here's a code snippet showing how this is typically done.

option(USE_SYSTEM_GRPC "Use system installed gRPC" OFF)
  # Find system-installed gRPC
  find_package(gRPC CONFIG REQUIRED)
  # Build gRPC using FetchContent or add_subdirectory

Full example


If your project does not use CMake (e.g. you're using make directly), you can first install gRPC C++ using CMake, and have your non-CMake project rely on the pkgconfig files which are provided by gRPC installation. Example

make (deprecated)

The default choice for building on UNIX based systems used to be make, but we are no longer recommending it. You should use bazel or cmake instead.

To install gRPC for C++ on your system using make, follow the Building gRPC C++ instructions to build from source and then install locally using make install. This also installs the protocol buffer compiler protoc (if you don't have it already), and the C++ gRPC plugin for protoc.

WARNING: After installing with make install there is no easy way to uninstall, which can cause issues if you later want to remove the grpc and/or protobuf installation or upgrade to a newer version.

Packaging systems

We do not officially support any packaging system for C++, but there are some community-maintained packages that are kept up-to-date and are known to work well. More contributions and support for popular packaging systems are welcome!

Install using vcpkg package

gRPC is available using the vcpkg dependency manager:

# install vcpkg package manager on your system using the official instructions
git clone
cd vcpkg
./vcpkg integrate install

# install gRPC using vcpkg package manager
vcpkg install grpc

The gRPC port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
