WIP: Set default Qt to 5.12.8

[mleotta]

This is a test to see if CI can build Qt 5.12.8

Fletch KWIVER against Fletch Mac build succeeded.

Fletch KWIVER against Fletch Windows build succeeded.

FWIW, the build errors on the Linux CI match the issues I've had building 5.12.8. I've beat on it before without resolution. It appeared to me that I was missing some package that Qt wanted but which package wasn't really as obvious as one would think considering the error messages.

ERROR: Feature 'xkbcommon' was enabled, but the pre-condition 'libs.xkbcommon' failed.

ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && features.xkbcommon && libs.xcb' failed.

ERROR: Feature 'fontconfig' was enabled, but the pre-condition '!config.msvc && features.system-freetype && libs.fontconfig' failed.

That's the same error I was seeing on my local linux build. It wasn't obvious to me either. @mwoehlke-kitware any ideas?

Do we know if anyone is actively using 5.12.8? If not we might be better off just jumping to the latest official Qt5, which looks to be 5.15.2. I have a patch for that, but was running into similar build errors.

For the record, my Windows build (VS 2019) has the following errors with this branch:

Other than I do vaguely recall now that we had such issues...

Maybe we should just try 5.15?

[mleotta]

I can push a branch for 5.15. I believe it will have similar issues, but if we are going to investing in fixing the issues maybe it would be better to get up to date with 5.15 anyway.
