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> 2017-10-27 21:43:34 +08:00			`# Defines a mapping from GCC_M_CPU to FPU`
