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 5: Integrating Third-Party Libraries and Dependency Management

So far, in this book, we have covered how to build and install our own code with CMake. In this chapter, we will take a look at how to use files, libraries, and programs that are not part of a CMake project. The first part of the chapter will be about how to find those things in general, while the latter part will focus on how to manage dependencies to build your CMake project.

One of the biggest advantages of using CMake is that it has built-in dependency management for the discovery of many third-party libraries. In this chapter, we will look at how to integrate libraries that are installed on your system and locally downloaded dependencies. Additionally, you will learn how third-party libraries can be downloaded and used as binaries and, alternatively, how they can be built from source directly out of a CMake project.

We will look at how to write instructions for CMake to reliably find almost any library...
