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 tests

Let us now discuss how to port tests from the reference build to our CMake build.

Getting started

If the project that is being ported contains a test target or any form of automated testing or test scripts, the first step will again be to run the traditional test step and record the commands used. For the Vim project, the place to start is src/testdir/Makefile. It will probably make sense to define tests on the CMake side close to src/testdir/Makefile and the test scripts, and we will choose to define tests in src/testdir/CMakeLists.txt. To process such a file, we must reference it in src/CMakeLists.txt:


We should also enable the test target in the top-level CMakeLists.txt, right...
