If there isn’t an installer for your Linux flavour then the best bet is to unpack it to a single separate directory and add that to your path in the Makefile. Also if you are compiling on an ARM machine (e.g. Pi4) be very careful that gcc-arm-none… include files don’t get replaced with with gcc-arm-linux… include files during compilation due to priority in the PATH. (just been there … don’t that ! argggh)
