  Same thing here:
  
    [ 94%] Building CXX object plugins/platforms/drm/CMakeFiles/KWinWaylandDrmBackend.dir/edid.cpp.o
    /data/kde/src/kwin/plugins/platforms/drm/edid.cpp:149:34: error: expected ')'
        QFile pnpFile(QStringLiteral(HWDATA_PNPIDS_FILE));

The correct syntax is `if NOT hwdata_DIR_NAMES OR NOT hwdata_PNPIDS_FILE)`

-NOTFOUND evaluates to FALSE [1]

This produces:

  #if HAVE_HWDATA
  /* #undef HWDATA_PNPIDS_FILE */
  #endif
