Hi all,
I need your help owing to a problem that succeeds in confusing me very much.
After about a month of delay, I tried to update my wonderful CRUX-kf5 OS
(anyhow, absolutely well working), but I get no success for 15 packages
(nearly all in KF5 port, and four - llvm, poppler, poppler-qt5, pango-32
- in other ports.

Are all these errors cmake related?

I've build opt/poppler and I see cmake outputs something. In your log I see nothing from cmake.

Does "revdep -vvv cmake" show any error?

You may try to rebuild cmake. Or, try the build commands of one of your failing ports manually : unpack the sources somewhere and run that cmake line. You should have a cmake log.
