Error during compiling ImageGStreamerQt.cpp

During compiling, i get this error message:

/opt/webkit/Source/WebCore/platform/graphics/gstreamer/ImageGStreamerQt.cpp:33:1: error: no declaration matches ‘WebCore::ImageGStreamer::ImageGStreamer(GstSample*)’
   33 | ImageGStreamer::ImageGStreamer(GstSample* sample)

      |       ^~~~~~~~~~~~~~

I can workaround it, by putting ImageGStreamer(GstSample* sample); into the public section of ImageGStreamer.h, but then at the final linking i will get an additional error message:

/usr/bin/ld: ../../lib/../Source/WebCore/CMakeFiles/WebCore.dir/platform/graphics/gstreamer/VideoFrameGStreamer.cpp.o: in function `WebCore::GstSampleColorConverter::convertSampleToImage(WTF::GRefPtr<_GstSample> const&)':
/opt/webkit/Source/WebCore/platform/graphics/gstreamer/ImageGStreamer.h:42: undefined reference to `WebCore::ImageGStreamer::ImageGStreamer(WTF::GRefPtr<_GstSample>&&)'

OS is Debian 11, AMD64. Compiler is GCC 10. Qt is 5.15.2.
