Within the CMake build system, accessing specific attributes of a build target (like an executable or library) is achieved through a dedicated command. This access allows retrieval of information such as compiler flags, include directories, linked libraries, and other build properties. For example, one might retrieve the location of a compiled library to use in another part of the build process.
This functionality is essential for creating flexible and robust build scripts. It allows developers to dynamically configure build processes based on target properties, facilitating complex projects and platform-specific customizations. Historically, managing such metadata within build systems has been challenging. Modern tools like CMake simplify this process considerably, improving build maintainability and reducing potential errors.
