To get the most out of this book

Basic familiarity with C++ and Unix-like systems is assumed throughout the book. Although this isn't a strict requirement, it will prove helpful in fully understanding the examples given in this book.

This book targets CMake 3.20, but most of the techniques described should work from CMake 3.15 (features that were added after are usually highlighted).

All examples have been tested on Debian with the following packages installed:

clang-format clang-tidy cppcheck doxygen g++ gawk git graphviz lcov libpqxx-dev libprotobuf-dev make pkg-config protobuf-compiler tree valgrind vim wget

To experience the same environment, it is recommended to use the Docker images, as explained in Chapter 1.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
