To get the most out of this book
Basic familiarity with C++ and Unix-like systems is assumed throughout the book. Although Unix knowledge isn’t a strict requirement, it will prove helpful in fully understanding the examples given in this book.
This book targets CMake 3.26, but most of the techniques described should work from CMake 3.15 (features that were added after are usually highlighted). Some chapters have been updated to CMake 3.28 to cover the latest features.
Preparation of the environment to run examples is covered in Chapters 1-3, but we specifically recommend using the Docker image provided with this book if you’re familiar with this tool.
