Integrating Clang-Format into the build system

In today’s software development landscape, CMake stands as a de facto industry standard for build systems. It offers a powerful and flexible way to manage builds across different platforms and compilers. Integrating Clang-Format – a tool for automatically formatting C++ code – into your CMake build process can help ensure consistent code formatting across your project. In this section, we’ll delve into how this can be achieved effectively.

First, you must start by identifying the Clang-Format executable on your system using CMake’s find_program() function:

# Find clang-format
find_program(CLANG_FORMAT_EXECUTABLE NAMES clang-format)

Next, you must gather all the source files you wish to format. The file(GLOB_RECURSE ...) function is useful for this purpose:

# Gather all source files from the root directory recursively
file(GLOB_RECURSE ALL_SOURCE_FILES
    *.cpp
