(In reply to Marcus R�ckert from comment #2) > maybe use the definition from cmake everywhere? To me it looks like with the use of %__builder, the %make_jobs macro is now cmake-specific. It should IMO be renamed. %make_jobs should just invoke plain make with arguments, where that is defined then should not matter. Once that is done, the definition from macros.kde4 and macros.qt5 can be removed.
