It’s not the compiler that knows, it is proffieos:

          struct NoBladeID {
            float id() { return 0.0; }
          };
          
          
// Define the default blade ID class.
          
          
#ifndef BLADE_ID_CLASS
          
          
#ifdef TEENSYDUINO
          #define BLADE_ID_CLASS InternalPullupBladeID<bladeIdentifyPin>
          #elif PROFFIEBOARD_VERSION - 0 >= 3
          #define BLADE_ID_CLASS BridgedPullupBladeID<bladeIdentifyPin, bladePin>
          #elif defined(PROFFIEBOARD_VERSION)
          #define BLADE_ID_CLASS SnapshotBladeID<bladeIdentifyPin>
          #else
          #define BLADE_ID_CLASS NoBladeID
          #endif
          
          
#endif  // BLADE_ID_CLASS
          
          
#ifdef BLADE_ID_TIMES

If no BLADE_ID_CLASS is defined, it uses a default which depends on what board you are compiling for.
