Is this supposed to allow someone like me to run
make px4_fmu-v5_default bloaty_compare_master?

If so it doesn't work for me
ninja: error: unknown target 'bloaty_compare_master'

@dakejahl You should already be able to do that (probably missing bloaty from your path): https://dev.px4.io/master/en/setup/building_px4.html#bloaty_compare_master

@hamishwillee Thank you! Haha I was like "but I've done that, I can type bloaty and it works".... I made a bash alias to bloaty/build/bloaty 🤦‍♂️
