I generaged renamed cygQt5Network-5.dll as cygQt5Network-5-gnuplot.dll and linked against it.
(Downgrade gcc-11 to gcc-10 is required for qt-5.9.4 build

The qt terminal works.

   error messages are shown in interactive session. 
   For example,
     terminal type is now 'qt'
     gnuplot> pl x
     QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-user'
     libGL error: Windows-DRI extension not available
     libGL error: No matching fbConfigs or visuals found
     libGL error: failed to load driver: swrast
     gnuplot> QXcbShmImage: shmget() failed (88: Function not implemented) for size 1394424 (642x543)
   For QStandardPaths error, the message is supressed if the environmental variable XDG_RUNTIME_DIR to
   /tmp/runtime-user like 
     export XDG_RUNTIME_DIR=/tmp/runtime-user
   For libGL errors, the messages are supressed if the environmental variable LIBGL_ALWAYS_INDIRECT to 1 like
     export LIBGL_ALWAYS_INDIRECT=1
   For QXcbShmImage: shmget() failed, the message is surpressed if cygserver service is running.
   Right click terminal launcher and run as administrator and execute below
      $ cygserver-config
      /etc/cygserver.conf
      is produced and then execute
      $ cygrunsrv -S cygserver
      Then cygserver service is registered to registry.
