Congrats on moving forwards, thanks for the work.

Linking to external docs (mainly the Qt ones) seems missing. For that 
respective doxygen tags files need to be added. Qt generates such files during 
the build, so for the current api.kde.org people copied those tags files from 
their distribution's package.

Here I did for updating to Qt 5.15:
https://invent.kde.org/websites/quality-kde-org/-/commit/
8a18c9033751cb41548361aea5c8ba2de3499dd7

with the files found in /usr/share/doc/packages/qt5/*/*.tags, provided by the 
package libqt5-qtdoc-devel on openSUSE TW.

To see how kapidox is instructed about those tags files, as that seems missing 
from its own docs, see the usage example in the current api.kde.org scripts:

kapidoxgendox.sh#L33
