Description Dan Horák 2017-05-10 10:07:15 UTC 
qt5-qt3d 5.9 fails to build on ppc64 and s390x in koji. First problem is that the bundled assimp is used for the build (visible in build.log), likely it misses fixes from our package. Second problem is why the system assimp can't be used, I did a local rebuild and found following in the cmake logs (qt3d-opensource-src-5.9.0-beta3/s390x-redhat-linux-gnu/config.log)

The p2t::CDT class should be coming from the poly2tri package. Probably there is a difference in poly2tri between the arches.
