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).

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.

This sample showcases efficient utilization of SMP system
with processing of independent resource-hungry workloads.
With no cross-dependencies between workers and no usage of shared
resources (during heavy-lifting itself) we may demonstrate almost
linear scaling of efficiency. I.e. 2 cores do the same amount of
calculations twice faster than only 1 core. 4 cores complete
the same calculations 2 times faster than 2 cores.
