    Add workaround for compilation using C++17 standard library
    
    As explained in #102 by @Pi-Cla and @uliw, `pdf-tools` relies on
    private headers provided by `poppler`. In order to compile these
    correctly, we need the standard library provided by C++17.
    
    `pdf-tools` is built and tested against C++11. This workaround
    provides the correct CXXFLAGS to compile the library and fixes the
    immediate broken compilation problem.
    
    There should be two "correct" fixes to these:
    1. Remove dependence on private `poppler` headers. This is being
    tracked in #103 and #105
    2. Upgrade `pdf-tools` to build and run against new C++ versions. This
    is being tracked in #109.
    
    Closes: #70, #76, #102, #108, politza/pdf-tools#706.
