This is likely due to compiling a couple of files that aren't necessary for 700D/E/1600 support (the SM1000 build explicitly enumerates each file brought in from Codec2 instead of just using CMake's project include functionality, so no warnings there). No action needed for now, just tracking in case we decide to fix this later.
