Hands-on exercises for a brief CMake tutorial.

The exercises are adapted from the dev-cafe/cmake-cookbook repository and the CodeRefinery CMake lesson.

CMake Cookbook offers a more in-depth discussion of many additional topics.

Introductory slides are rendered here.

Example 1

Introduce basic CMake commands to successfully compile a project. We will also show how to work with dependencies and switch generators.

Commands discussed:

• project
• cmake_minimum_required
• message
• set
• option
• if
• add_executable
• find_package
• target_link_libraries
• target_sources

Example 2

We will discuss how to structure a project and how to produce libraries, in addition to executables.

Commands discussed:

• add_library

Example 3

We will have a first look at the Catch2 unit test framework and how to use it with CTest.

Example 4

CMake is not just for C/C++, it can be used also for Fortran projects. In this example we will build a C++/Fortran project. We will also get acquainted with CTest, the testing framework that is part of the CMake suite.

Example 5

This final example will focus on unit testing and present some of the available C++ frameworks. We will focuse on Catch2 and introduce some of its features.
