Antares : Linux Kernel Like Build-System For ARM (STM32), MSP430, AVR, etc.

Quoting from Gihub itself

ANTARES is an all-in-one buildsystem, aimed at baremetal targets. It is designed to be portable across a lot of MCUs and adding another MCU is trivial. It uses Kconfig as seen in linux kernel and a set of homebrew Makefiles designed to ease the development process. This stuff is still pre-alpha quality, so if things don't work for you out of the box - drop me a line, or create an issue on github
