Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

USB HID Sample Application
##########################
Overview
********
This sample app demonstrates use of a USB Human Interface Device (HID) driver
by the Zephyr project. This very simple driver is enumerated as a raw HID
device. This sample can be found under :zephyr_file:`samples/subsys/usb/hid` in the
Zephyr project tree.
Requirements
************
This project requires a USB device driver.
Building and Running
********************
This sample can be built for multiple boards, in this example we will build it
for the reel_board board:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/usb/hid
:board: reel_board
:goals: build
:compact:
After you have built and flashed the sample app image to your board, plug the
board into a host device, for example, a PC running Linux.
The board will be detected as shown by the Linux journalctl command:
.. code-block:: console
$ journalctl -k -n 10
usb 7-1: New USB device found, idVendor=2fe3, idProduct=0100
usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 7-1: Product: Zephyr HID sample
usb 7-1: Manufacturer: ZEPHYR
usb 7-1: SerialNumber: 0.01
input: ZEPHYR Zephyr HID sample as /devices/platform/vhci_hcd.0/usb7/7-1/7-1:1.0/0003:2FE3:0100.0046/input/input81
hid-generic 0003:2FE3:0100.0046: input,hidraw0: USB HID v1.10 Device [ZEPHYR Zephyr HID sample] on usb-vhci_hcd.0-1/input0
You can monitor report sending using standard Linux ``usbhid-dump`` command.
.. code-block:: console
$ sudo usbhid-dump -d 2fe3:0100 -es
