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.

NFC Sample App
--------------

This is a simple application to test an elementary signal-through
with NFC module connected to the second UART.


Build and run
-------------

To test the serial line routines, open a terminal window and type:

	nc -l 8888

Open another terminal window and type:

For QEMU x86:
	mkdir build; cd build
	cmake -DBOARD=qemu_x86 ..
	make run

For QEMU ARM:
	mkdir build; cd build
	cmake -DBOARD=qemu_cortex_m3 ..
	make run


Sample output
-------------

Write some random text on the nc terminal window. The terminal
window running qemu must display:

For QEMU x86:

[QEMU] CPU: qemu32
Sample app running on: x86
uart1_init() done
uart1_isr: 61 73 64 73 61 64 73 0a (8 bytes)

For QEMU ARM:
