CMake Build with Protobuf on Windows

To build Visual C++ projects on Windows that has dependency on Google protobuf library, we can use CMake. The executable of protobuf is not sufficient to compile C++ projects. 

Dependency on protobuf

To specify a dependency on protobuf, the following line can be added into CMakeLists.txt file:

find_package(Protobuf REQUIRED)

Install protobuf library on Windows

1. Follow this article to install Microsoft vcpkg on Windows: Microsoft vcpkg C++ Library Manager 
2. Install protobuf library using the following command:
   

   vcpkg install protobuf:x64-windows

3. Wait until the installation is completed:
   
   

Test the dependency

1. Create a test CMake project with the following lists (CMakeLists.txt):
   

   cmake_minimum_required(VERSION 3.10)
   
   # set the project name
   project(Test)
   
   # Find package
   find_package(OpenSSL REQUIRED)
   find_package(Protobuf REQUIRED)

2. Run the build command (under project folder path, for my environment, it locates in C:\hdp\cmaketest):
   

   cmake .

3. The output looks like the following:
   

   C:\hdp\cmaketest>cmake .
