qt5-* have been updated to 5.5 in epel7 since eyesight was rebuilt, but the current epel7 version does not build against 5.5. Either this needs to be rebased to 0.1.4 as in Fedora, or the upstream commit which fixes the compile error needs to be backported and added.
CentOS is in the process of building EPEL for AArch64, so it would help if this were fixed one way or another.
Than, This would be fixed by your update: https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2015-96834ab84a Any reason this isn't stable yet?
Update has been pushed to stable; closing.
