Integrating Google Test into a C++ project

We’re going to demonstrate how to incorporate Google Test into a CMake project, providing a step-by-step guide to configuring CMake to work with Google Test for unit testing in C++ projects.

To start, ensure that Google Test is included in your project. This can be done by adding Google Test as a submodule in your project’s repository or downloading it via CMake. Once Google Test is part of your project, the next step is to configure your CMakeLists.txt file to include Google Test in the build process.

Here’s an example of how you might configure your CMakeLists.txt file to integrate Google Test via a submodule:

git submodule add https://github.com/google/googletest.git external/googletest

Update CMakeLists.txt to include Google Test and Google Mock in the build:

# Minimum version of CMake
cmake_minimum_required(VERSION 3.14)
project(MyProject)
# GoogleTest requires at least C++14
set(CMAKE_CXX_STANDARD...
