Overview of this book

Minimal CMake guides you through creating a CMake project one step at a time. The book utilizes the author's unique expertise in game and engine development to craft compelling examples of how CMake can be used to build complex software. The chapters introduce concepts gradually, each one building on the last. Throughout the course of the book, you will progress from a simple console application all the way through to a full windowed app. The book will help you build a strong foundation in CMake that will translate to future projects. You'll learn how to integrate existing software libraries to enhance your app's functionality, how to build reusable libraries to share with others, and how to manage developing for multiple platforms simultaneously, including macOS, Windows, and Linux. You'll also find out how CMake facilitates testing and how to package your application ready for distribution. The book aims to not overwhelm you with everything there is to know about CMake. Instead, it focuses on the most relevant and important parts that will help you become productive quickly. By the end of this book, you will be a confident CMake user and will have gained the skills and experience to build and share your own libraries and applications.

Adding install support to a library

When adding install support to a library, everything revolves around the install command. The install command is how we tell CMake what to install, as well as the relative layout of files. The good news is there’s very little to change in our existing CMakeLists.txt files, and in most cases, there’s not a great deal to add either. What we do add though can be quite confusing at first glance, which we’ll try to demystify here.

As with earlier chapters, we’ll work through a concrete example and show how to add install support to the simplest of our existing libraries, mc-array. This is a static library that provides support for a resizable array in C (very similar to std::vector in C++). We’ve used this throughout our Game of Life application and it’s a particularly useful utility to rely on.

We’ll start by looking at ch7/part-1/lib/array/CMakeLists.txt. The first change is we’ve now committed...
