Compile-time Dependencies

You will need a c++11 compiler, cmake, and the “development” editions of the libraries used (boost, poppler, qt5).

The exact names of those packages will vary based on your operating system and/or distribution, but development versions often end in -dev, -headers or similar.

If your distribution does not yet have a package for dspdfviewer, you might want to consider packaging it, so that in the future, you (and other users of your distribution) can simply install the package.

Debian and Ubuntu based systems

The following package list works on current debian-based systems:

sudo apt install libboost-program-options-dev libboost-test-dev \
     libpoppler-qt5-dev qtbase5-dev qttools5-dev qttools5-dev-tools

Fedora
