CMake Cookbook

By: Radovan Bast, Roberto Di Remigio

Overview of this book

CMake is cross-platform, open-source software for managing the build process in a portable fashion. This book features a collection of recipes and building blocks with tips and techniques for working with CMake, CTest, CPack, and CDash. CMake Cookbook includes real-world examples in the form of recipes that cover different ways to structure, configure, build, and test small- to large-scale code projects. You will learn to use CMake's command-line tools and master modern CMake practices for configuring, building, and testing binaries and libraries. With this book, you will be able to work with external libraries and structure your own projects in a modular and reusable way. You will be well-equipped to generate native build scripts for Linux, MacOS, and Windows, simplify and refactor projects using CMake, and port projects to CMake.

Introduction

Projects often depend on other projects and libraries. This chapter demonstrates how to detect external libraries, frameworks, and projects and how to link to these. CMake has a rather extensive set of prepackaged modules to detect the most commonly used libraries and programs, such as Python and Boost, for example. You can get a list of existing modules using cmake --help-module-list. However, not all libraries and programs are covered and from time to time you will have to provide your own detection scripts. In this chapter, we will discuss the necessary tools and discover the find family of CMake commands:

  • find_file to find a full path to a named file
  • find_library to find a library
  • find_package to find and load settings from an external project
  • find_path to find a directory containing the named file
  • find_program to find a program
You can use the --help-command...
