I do have libpoppler-qt5-1:
dpkg -l libpoppler-qt5-1
ii libpoppler-qt5-1:amd6 0.26.5-2+deb8u1
and libpoppler-qt5.so.1: /usr/lib/x86_64-linux-gnu/libpoppler-qt5.so.1
The command to build the package. I first went with:
apt-get -b source libpoppler64=0.48.0-2
but also tried:
dpkg-buildpackage -rfakeroot -uc -b
