24 Zephyr's build system is based on `CMake`_.
26 The build system is application-centric, and requires Zephyr-based applications
27 to initiate building the Zephyr source code. The application build controls
28 the configuration and build process of both the application and Zephyr itself,

91 Once an application has been defined, you will use CMake to generate a **build
92 directory**, which contains the files you need to build the application and
94 The easiest way to do this is with :ref:`west build <west-building>`, but you
95 can use CMake directly also. Application build artifacts are always generated
96 in a separate build directory: Zephyr does not support "in-tree" builds.
