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 6, Automatically Generating Documentation

  1. Doxygen is the de facto standard of documentation generation tools for C and C++ projects.
  2. Since CMake already provides a find module for Doxygen, this can be done by using the find_package(...) CMake command.
  3. Yes – Doxygen can draw graphs, given that graphing software such as DOT, Graphviz, and PlantUML are available in the environment. To enable DOT graphing, setting HAVE_DOT to TRUE is sufficient. For PlantUML, PLANTUML_JAR_PATH needs to be set to the path that contains the plantuml.jar file.
  4. @startuml and @enduml.
  5. PLANTUML_JAR_PATH needs to be set to the path that contains the plantuml.jar file.
  6. With the help of the install(DIRECTORY) command.
