Your linking error occurs because you're missing -lfreetype. When
static linking you need to include the linker flags for all the
dependencies. Unfortunately poppler does not correctly record it's
private dependencies in the pkg-config file, but try linking with
these flags:

   pkg-config --libs --static poppler-cpp cairo lcms2 libopenjp2 libtiff-4
