Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code commands in text, folder names, filenames, module names, and target names.

A block of code is set as follows:

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

project(recipe-01 LANGUAGES CXX)

add_executable(hello-world hello-world.cpp)

Any command-line input is written in bold and contains a $ prompt in front of the command to type:

$ mkdir -p build
$ cd build
$ cmake ..

To distinguish command-line input and output, we keep output non-bold:

$ ./hello-world

Hello World!
