I got this error trying to compile the current master (dbac1b9):

What version of Qt are you using? (qmake --version)

[promi]

QMake version 3.1
Using Qt version 5.14.2 in /usr/lib64

Just checked the code and it seems as if I have forgotten to actually include it. And since it's hidden by the preprocessor by default, the CI didn't detect it.

Thanks for reporting, I'll push a fix :)

[Krzmbrzl]

Could you verify that #4229 fixes the compile error for you? I don't have the time to re-compile Mumble right now...

Works fine now, thanks.
