I am attempting to build the tool from this repo: https://github.com/taurus-forever/diffpdf-console
It requires the headerfile poppler-qt4.h to run its Makefile, which is supposedly included in some poppler dependency. The problem here is that I've installed every poppler dep I can think of from apt-get, and still can't find it. The dep "python-poppler-qt4" seems to be what I'm looking for, but I cannot locate the package on Ubuntu 18.04.
Google isn't helping. Does anyone know how to install the dep for poppler-qt4 on Ubuntu 18.04?
