Torsten Rasmussen 407b49b35c cmake: use find_package to locate Zephyr
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.

Title: Entropy

Description:

Sample for the entropy gathering driver

--------------------------------------------------------------------------------

Building and Running Project:

This project writes an infinite series of random numbers to the
console, 9 per second.

It can be built and executed on frdm_k64f as follows:

    make

Sample Output:
