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.

Detecting the MPI parallel environment

The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-03/recipe-06 and has a C++ and C example. The recipe is valid with CMake version 3.9 (and higher) and has been tested on GNU/Linux, macOS, and Windows. In https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-03/recipe-06, we also provide a C example compatible with CMake 3.5.

An alternative and often complementary approach to OpenMP shared-memory parallelism is the Message Passing Interface (MPI), which has become the de facto standard for modeling a program executing in parallel on a distributed memory system. Although modern MPI implementations allow shared-memory parallelism as well, a typical approach in high-performance computing is to use OpenMP within a compute node combined with MPI across compute nodes. The implementation...
