CMake Variables

CMake variables are placeholders used in CMake scripts to store and manage information, such as file paths, compiler options, or project settings. Think of them as labeled boxes that hold specific details needed for building software. By using these variables, developers can write more flexible and organized build configurations. For example, instead of hardcoding a file path multiple times, they can set it in a variable and refer to it whenever needed. This makes the configuration easier to maintain and adapt for different environments or build scenarios.
