Kconfiglib with CMake build

CMake build support for Kconfiglib library. This project supports CMake and C header file generation from Kconfig file with default configuration support (E.g. Kconfig.defaults).

• Generated CMake and C header files are placed in ${CMAKE_BINARY_DIR}/config
• CMake file is included to project (to customize build) at kconfig.cmake
• C Header file path is included to project at kconfig.cmake
• Updated configuration file (sdkconfig) generated at project directory

Prerequisties

• Copy cmake and scripts into project
• Create 'SCRIPTS_DIR' cmake variable with scripts folder location. E.g. set(SCRIPTS_DIR ${CMAKE_SOURCE_DIR}/scripts)
• Include python and kconfig in project cmake file. E.g. include(${CMAKE_SOURCE_DIR}/cmake/python.cmake) and include(${CMAKE_SOURCE_DIR}/cmake/Kconfig.cmake)
• Update below cmake variables if required in kconfig.cmake

set(CONFIG_OUTPUT_DIR ${CMAKE_BINARY_DIR}/config)

set(KCONFIG_INPUT  Kconfig)
set(CONFIG_PROJECT sdkconfig)
set(CONFIG_DEFAULT sdkconfig.defaults)

Launch menuconfig

• Run cmake --build build_output_path --target menuconfig to launch menuconfig in terminal
