Sebastian Bøe 55ee53ce91 cmake: Prepend 'cmake_minimum_required()' into 'app' build scripts
Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.

Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.

To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.

This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.

The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

Title: USB Console Hello World

Description:

A simple Hello World example, with console output coming to USB UART. Primarily
intended to show the required config options.

Usage
-----
Plug the board into a host device, for example, a PC running Linux.
The board will be detected as a CDC_ACM serial device. To see the console output
from the zephyr board, use a command similar to "minicom -D /dev/ttyACM0".
You may need to stop modemmanager via "sudo stop modemmanager", if it is
trying to access the device in the background.

Building and Running Project:

Refer to https://www.zephyrproject.org/doc/boards/x86/arduino_101/doc/board.html
for details on flashing the image into an Arduno 101.
