Subject: [PATCH] PdfImport: Fix compile with newer poppler

Brings a dependency on poppler-qt5 to be able to include the version
header, honestly it's not strictly needed, one could do a
check_cxx_source_compiles, but I don't care about Calligra enough to
spend more time making it compile while it's using poppler the wrong
way.
