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. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no> |

.. _vl53l0x:
VL53L0X: Time Of Flight sensor
##############################
Overview
********
This sample periodically measures distance between vl53l0x sensor
and target. The result is displayed on the console.
It also shows how we can use the vl53l0x as a proximity sensor.
Requirements
************
This sample uses the VL53L0X sensor controlled using the I2C interface.

Building and Running
********************
This project outputs sensor data to the console. It requires a VL53L0X
sensor, which is present on the disco_l475_iot1 board.
