Anyway, when I > install cups-filters-1.25, then also libqpdf.so.26 is required at runtime. ... and if you look at build.o.o https://build.opensuse.org/package/show/Printing/cups-filters you see that the builds for 15.0 and 15.1 fail because of a missing build dependency to qpdf-devel >= 8.3.0. That's why I also copied qpdf to my home project to resolve this dependency.
