Using CMake via a command-line interface
The most common way of using CMake is via the command-line interface (CLI). CLIs exist in virtually every environment, thus, learning to use CMake in a CLI is essential. In this section, we are going to learn how to perform the most basic CMake operations using the CLI.
Interactions with the CMake CLI can be done by issuing the
cmake command in your operating system's terminal, assuming that CMake is installed and the

If your terminal is complaining about a missing command, then you should either install CMake (explained in Chapter 1, Kickstarting CMake) or make it discoverable by adding it to your system's
PATH variable. Consult your operating system's guide about...
