Overview of this book

Creating top-notch software is an extremely difficult undertaking. Developers researching the subject have difficulty determining which advice is up to date and which approaches have already been replaced by easier, better practices. At the same time, most online resources offer limited explanation, while also lacking the proper context and structure. This book offers a simpler, more comprehensive, experience as it treats the subject of building C++ solutions holistically. Modern CMake for C++ is an end-to-end guide to the automatization of complex tasks, including building, testing, and packaging. You'll not only learn how to use the CMake language in CMake projects, but also discover what makes them maintainable, elegant, and clean. The book also focuses on the structure of source directories, building targets, and packages. As you progress, you’ll learn how to compile and link executables and libraries, how those processes work, and how to optimize builds in CMake for the best results. You'll understand how to use external dependencies in your project – third-party libraries, testing frameworks, program analysis tools, and documentation generators. Finally, you'll get to grips with exporting, installing, and packaging for internal and external purposes. By the end of this book, you’ll be able to use CMake confidently on a professional level.

Understanding generator expressions

CMake builds the solution in three stages – configuration, generation, and running the build tool. Generally, we have all the required data during the configuration stage. But every once in a while, we encounter the chicken and the egg problem. Take an example from the previous section – a target needs to know the path of a binary artifact of another target. But that information is only available after all the list files are parsed and the configuration stage is complete.

How do we deal with that kind of problem? We could create a placeholder for that information and postpone its evaluation to the next stage – the generation stage.

This is what generator expressions (sometimes called genexes) do. They are built around target properties such as LINK_LIBRARIES, INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS, propagated properties, and many others, but not all. They follow rules similar to conditional statements and variable evaluation...
