This issue was fixed in upstream in commit https://github.com/mchehab/zbar/commit/d6578fc54bebf93a7dd463da2030593588b8445e which is part of 0.23.90 release.

The problem was that configure did not detect moc utility

checking for Qt5Core >= 5 Qt5Gui >= 5 Qt5Widgets >= 5.0 Qt5X11Extras >= 5.0... yes
checking for moc-qt5... no
checking for moc... no
configure: using moc from 
configure: using Qt version 5.15.2

which was missing in commands creating qt/moc_%.cpp files. Iqt is first argument, the command should be called like `moc Iqt ...`.
