Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

For CMSIS we now have HAS_CMSIS which needs to be added to the
SoC definition.
Instead of changing the main Makefile we now include a sub-Makefile
with all related header and library paths that are hosted in
ext/
Move redifintion of LIB_INCLUDE_DIR later to get variables defined
in Makefile.toolchain.*

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) defines a
set of standard interfaces to ARM Cortex-M SOCs. In particular, the CMSIS-CORE
component standardizes the software interface to core and peripheral registers,
as well as exception names and the system clock frequency. Multiple SOC
vendors, including NXP and Nordic Semiconductor, include the CMSIS-CORE header
files in their SOC header files. These SOC header files are in turn used by
the vendor's peripheral drivers.
