- CMake build process handles dependencies much more effectively
- Cleaner separation of test and binary builds
- permit co-existing test and multiple architecture builds
- add support for AVR from cmake-avr:
https://github.com/mkleemann/cmake-avr
- new build process avoids creating files in the src directory
