No, this is not possible since the Debian builds do not contain the
MuPDF plug-in which is also considered experimental and hence a
build-time option only.

I think those compilation errors are due to the MuPDF version being
older than what the current plug-in source code is programmed against.
It should for example be compatible with MuPDF version 1.7, which you
would need to build from source as well. (There was a recent question
[1] about doing this on Debian which might be useful to you.)

Best regards, Adam.

P.S.: The plug-in is considered experimental since it needs a dedicated
maintainer, which is especially necessary since the MuPDF/Fitz API is
still changing rather rapidly as you experienced.

P.P.S.: I am also posting this to the qpdfview mailing list since it
seems useful to have this information publicly available.
