Overview of this book

CMake is a powerful tool used to perform a wide variety of tasks, so finding a good starting point for learning CMake is difficult. This book cuts to the core and covers the most common tasks that can be accomplished with CMake without taking an academic approach. While the CMake documentation is comprehensive, it is often hard to find good examples of how things fit together, especially since there are lots of dirty hacks and obsolete solutions available on the internet. This book focuses on helping you to tie things together and create clean and maintainable projects with CMake. You'll not only get to grips with the basics but also work through real-world examples of structuring large and complex maintainable projects and creating builds that run in any programming environment. You'll understand the steps to integrate and automate various tools for improving the overall software quality, such as testing frameworks, fuzzers, and automatic generation of documentation. And since writing code is only half of the work, the book also guides you in creating installers and packaging and distributing your software. All this is tailored to modern development workflows that make heavy use of CI/CD infrastructure. By the end of this CMake book, you'll be able to set up and maintain complex software projects using CMake in the best way possible.

Chapter 3: Creating a CMake Project

By now, you should be familiar with how to use CMake and its basic concepts, such as the two-stage build. So far, we have only looked at how CMake is used with code that already exists, but the more interesting part is when it comes to building an application using CMake. In this chapter, you will learn how to build executables and libraries and how to use them together. We will have an in-depth look at creating different kinds of libraries and we will present some good practices about how to structure CMake projects. As libraries often come with a variety of compiler settings, we will learn how we can set them and pass them onto dependent libraries if necessary. Since dependencies in projects can get quite complicated, we will also learn how to visualize the dependencies between the different targets.

In this chapter, we will cover the following topics:

  • Setting up a project
  • Creating a "hello world" executable
  • Creating...
