Best Practices

Introduction

Writing clean and maintainable CMake code is essential for large projects. In this lesson, we’ll cover:

  • Modular CMake: Organize your project into modules.
  • Target-Based Design: Use targets instead of global variables.
  • Versioning: Specify minimum CMake versions and project versions.

Key Concepts

  • Modular CMake: Break your project into smaller, reusable modules.
  • Target-Based Design: Use targets to manage dependencies and properties.
  • Versioning: Use project(MyProject VERSION 1.0.0) to specify project versions.

Code Sample

cmake_minimum_required(VERSION 3.10)
project(MyProject VERSION 1.0.0)

add_subdirectory(src)
add_subdirectory(lib)

Quiz

Why is modular CMake important?

Modular CMake makes your project easier to maintain and scale.

What is the benefit of using target-based design?

Target-based design avoids global variables and makes dependencies explicit.

How do you specify a project version in CMake?

You specify a project version using project(MyProject VERSION 1.0.0).
