# File to tweak compiler settings before compiler detection happens (before project() is called)
# We dont have PAL enabled at this point, so we can only use pure-CMake variables

# if we are in Script Only ("Quick Start") Mode, we override the compiler with a do-nothing fake one
# doing so is slightly different on each platform, so it uses a different file each.
