Marc Herbert 2cd51a33ce samples: make find_package(Zephyr...) REQUIRED 
This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry. See parent commit for more details (split from parent for
better readability).

X-NUCLEO-IKS01A1: MEMS inertial and environmental multi-sensor shield
#####################################################################

Overview
********
This sample enables all sensors of a X-NUCLEO-IKS01A1 shield, and then
periodically reads and displays data from the shield sensors:

- HTS221: Temperature and humidity
- LPS25HB: Atmospheric pressure
- LIS3MDL: 3-axis Magnetic field intensity
- LSM6DSL: 3-Axis Acceleration

Requirements
************

This sample communicates over I2C with the X-NUCLEO-IKS01A1 shield
stacked on a board with an Arduino connector. The board's I2C must be
configured for the I2C Arduino connector (both for pin muxing
and devicetree).
Please note that this sample can't be used with boards already supporting
one of the sensors available on the shield (such as disco_l475_iot1) as zephyr
does not yet support sensors multiple instances.

Building and Running
********************

This sample runs with X-NUCLEO-IKS01A1 stacked on any board with a matching
Arduino connector. For this example, we use a :ref:`nucleo_f429zi_board` board.
