Install make using the following command:

.. code-block:: bash

   choco install make

Once installed, build the application as normal.

Manual Install Method
=====================

The pre-built make application can be downloaded from
https://gnuwin32.sourceforge.net/packages/make.htm by either getting both the
``Binaries`` and ``Dependencies`` and extracting them to the same folder, or
getting the ``Complete package`` setup. Once installed and in the path, build
the application as normal.
