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.

Porting install targets

We can now configure, compile, link, and test the code, but we are missing the install target, which we will add in this section.

This is the Autotools approach to building and installing code:

$ ./configure --prefix=/some/install/path
$ make
$ make install

And this is the CMake way:

$ mkdir -p build
$ cd build
$ cmake -D CMAKE_INSTALL_PREFIX=/some/install/path ..
$ cmake --build .
$ cmake --build . --target install

To add an install target, we add the following snippet in src/CMakeLists.txt:


In this example, we only install the executable. The Vim project installs a large number of files along with the binary (symbolic links and documentation files). To keep this section digestible, we don't install all other files in this example migration. For your own project, you should verify...
