I'm now seeing it in epel.

I think the qt5.6 vs qt5.9 issue is mainly about timing.  There is a 
delay between the release of rhel7.x and the appearance of the CentOS or 
SL rebuilds, and epel is usually kept in sync with rhel.  Some SL7 
users, including me, weren't seeing the 7.5 packages anyway.

I have just rebuilt my 30-pre-579 mythtv-master packages (from before 
the ffmpeg refactor) for the new SL7x environment, using mock in F26, 
and was able to install them under SL7.4.  They pulled in qt5.9 and 
several other packages; after that 'yum update' installed or updated 532 
more packages from SL7x and so far all seems good...
