unfortunately both doxywizard and octave need something more
and mixed versions seem to not work.

---------------------------------------
$ doxywizard
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-Marco'

** (doxywizard:2906): WARNING **: 15:23:21.164: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying
Cannot mix incompatible Qt library (5.9.4) with this library (5.15.18)
Aborted

Not the most helpful error message there, is it. Running doxywizard under gdb seems to indicate the problem may be with cygqxcb.dll. There seems to be a larger issue here: somehow the 5.15.18 DLLs are not present in /usr/bin after installing those released packages. The debug version of them are installed into /usr/lib/debug/usr/bin but the stripped non-debug version are missing. I will investigate further.

After the 5.15.18 DLLs get installed properly I can look into the version incompatibility problem.

Can you give an example of octave's issue? Wondering if it's the same thing or something else.
Thanks for the report!
