I curate my own lists of Octave dependencies, you can look at

  
https://salsa.debian.org/mtmiller/mtmiller-defaults/blob/master/debian/control#L99

or

  https://github.com/mtmiller/ansible-role-octave-dev/blob/master/vars/main.yml
  
https://github.com/mtmiller/ansible-role-octave-dev/blob/master/vars/Ubuntu-xenial.yml

(replace the last link with whichever codename of Ubuntu you are on).

This is now the default, so you don't need --with-qt at all.

Oh, I think I see why this is. You probably have qtchooser installed,
but Qt 4 is still the default. The other tools (moc, uic, etc) have
variables for the "-qt5" option to ensure we use the right version, but
it looks to me like QCOLLECTIONGENERATOR doesn't.

Can you verify by running

    $ qtchooser -print-env
    QT_SELECT="default"
    QTTOOLDIR="/usr/lib/qt5/bin"
    QTLIBDIR="/usr/lib/x86_64-linux-gnu"

You can apt install the "qt5-default" package if you want to bypass
this. But this is a case that we should address.
