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 9: Creating Reproducible Build Environments

Building software can be complex, especially when dependencies or special tools are involved. What compiles on one machine might not work on another because a crucial piece of software is missing. Relying on the correctness of the documentation of a software project to figure out all the build requirements is often not enough, and as a consequence, programmers spend a significant amount of time combing through various error messages to figure out why a build fails.

There are countless stories out there of people avoiding upgrading anything in a build or continuous integration (CI) environment because they fear that every change might break the ability to build the software. This goes as far as companies refusing to upgrade the compiler toolchains they are using for fear of no longer being able to ship products. Creating robust and portable information about build environments is an absolute game-changer. With presets, CMake provides...
