Old project broken after CubeMX split

Hi, so the recent change to make CubeMX a separate app has broken my old project. I am using a Nucleo board and HAL in the project. After a change to the .IOC file I get "stm32h7xx_nucleo_conf.h:50: warning: "USE_NUCLEO_144" redefined".

 

Is there a resource somewhere explaining to to do all of the after the CubeMX split?

Remove USE_NUCLEO_144 from the preprocessor defines in project properties.

Or ignore it, since it's not preventing compiling from working.

This was an issue before the split as well.
