As Denis said, you can easily use container images to get most of those
operating systems tested. Just be careful with containers that Qt 5.10 through
5.12.2 will not like being run on a kernel that is older than the distribution
usually ships with. By coincidence, I submitted a fix for that today.
But I don't think you need to test all GCC combinations, much less in each OS.
Compiling with the latest is usually sufficient for most cases, as usually the
compilers start catching things they didn't use to. Especially if you want to
be warning-clean, like Qt.
You'll likely need to test at least the oldest compiler you still support, to
make sure that you're not using some C++11/14/17 language or standard library
feature that the compiler lacks.

Here's where distribution packaging helps. When using Travis, I use Stephan
Binner's Qt PPAs.
With Travis, you can easily select between Ubuntu 12.04 (Trusty) and 14.04
(Xenial) by a simple line in the .yml file, so that will give you all the way
from 4.8.7 to 5.12.1.
I've never installed older versions of Qt using Homebrew (on macOS), so I
don't even know fi this is possible. I doubt they'll have really old stuff. As
for AppVeyor, they also have quite a few Qt versions (see ), but not
