[Re-adding the list, but I think dev is the wrong list]

QAbstractButton is irrelevant here. Your error message was 
QToolButton::checkStateSet() *specifically* wasn't defined. It's not expected to 
because it wasn't added until 6.3.

The only explanation I can come up with is that the headers don't match the 
library.

Indeed, so does it in mine:
$ nm -DC /usr/lib64/libQt5Widgets.so.5.15.13 | grep QToolButton::checkState
000000000038eb40 T QToolButton::checkStateSet()

That's a non-standard patch. It doesn't exist in the official 5.15.13 version.

Someone backported an extra patch onto that release (it's https://
invent.kde.org/qt/qt/qtbase/-/commit/f74d263ff7de636e00094040a795b0763af41772). 
I don't know why they did that, but that's not important. The diagnosis is the 
same: your headers don't match the library you have. You have to match.
