Introduction

In the previous chapters, we have discovered a number of building blocks to create projects configured and built using CMake. In this chapter, we will discuss how to combine these building blocks and introduce abstractions to avoid huge CMakeLists.txt files and minimize code repetition, global variables, global state, and explicit ordering. Our goal will be to present patterns for a modular CMake code structure and for limiting the scope of variables. We will discuss strategies that will also help us control CMake code complexity for medium to large code projects.
