You must set the following variables in order to build:
STM32CUBE_FW_PATH: Set this to the path of STM32CubeF4 (https://github.com/STMicroelectronics/STM32CubeF4.git)
UNITY_PATH: Set this to the path of Unity (https://github.com/ThrowTheSwitch/Unity)
You may also need to set this to point to your ARM GCC bin directory if arm-none-eabi-gcc is not on the path
