I did not try to build gnuplot 6.0 under Ubuntu, but on Mint I eventually
also ran into the problem that there is no package that contains the Qt6
moc and lrelease tools.   At any rate I couldn't find them with "apt-file".
The build process tries to use /usr/bin/moc and /usr/bin/lrelease but if
those are from a  Qt5 installation then it fails with the error message:
    This file was generated using the moc from 5.15.3.
    It cannot be used with the include files from this version of Qt.
