make is a famous build tool used to build makefiles. It is a part of gnu, specifically gcc (or MinGW if you're on Microsoft Windows), so you must have that installed first in order to use it.

The example below demonstrates how make can be used to build your project's binaries, along with creating a dedicated build directory and generating CMake:

mkdir build
cd build
cmake -GUnix-Makefiles ..
make

Where:

• build is a sub-directory under the project's main directory, created to store CMake's output/artifacts.
• The cmake .. command generates project's output (called on the project's main directory), which is actually makefiles used later by make.
• The make command builds the project using the makefiles in the build directory.

Note: The example above is written for *nix systems, mostly Linux. Syntax on Microsoft Windows is similar, yet may differ at some points, depending on the terminal at hand.
