Introduce cmake-based rewrite of KBuild 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 PR: zephyrproject-rtos#4692 docs: http://docs.zephyrproject.org/getting_started/getting_started.html Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no>

# Lots of duplications here.
# FIXME: maintain this only in one place.
# We need to separate actual toolchain from the host-tools required by Zephyr
# and currently provided by the Zephyr SDK. Those tools will need to be
# provided for different OSes and sepearately from the toolchain.
cmake: fix set_ifndef() usage patterns If the value argument to set_ifndef() may be unset, the entire value must be double-quoted to avoid a CMake syntax error. Fix call sites which don't handle this, or which otherwise make non-idiomatic use of this function. Signed-off-by: Marti Bolivar <marti@opensourcefoundries.com>

cmake: Fix SDK-less builds This change changes the semantics of the environment variable ZEPHYR_SDK_INSTALL_DIR to allow the use of 3rd party toolchains alongside the Zephyr SDK's host tools. Specifically, setting ZEPHYR_SDK_INSTALL_DIR now indicates that the Zephyr SDK host tools are to be used. But not necessarily that the Zephyr SDK's toolchain is to be used. The documentation is also changed to explain this behaviour. Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no>
