Anything else?

full error log is extremely long so I've just attached it as a file - if you'd rather I re-ran this without multithreading to make it easier to read, I can do that.

@pktiuk sorry to bug you with this but I'm guessing the fix is just a repeat of what you did way back in #382

slightly more readable (though still obscenely long) error log

Hi @cobalt2727,
thank you for report.
Could you tell me why versions lower than 5.10 should be still supported?
This version of library is not supported by QT and is shipped with systems like Ubuntu 18.04, which is also not supported anymore.

[cobalt2727]

I mean, if it's just not worth the effort to you, fair enough - I can get newer QT5 builds from a PPA pretty easily. 18.04 is technically still supported under the (free for non-commercial use) Ubuntu Pro plan until 2028: https://ubuntu.com/about/release-cycle

I think that ensuring compatibility with versions lower than 5.10 is too much hassle for too small number of systems.
It was my mistake, that I forgot to set this requirement in cmake
