[Interest] 5.11.0 documentation build bug?

[roland at logikalsolutions.com]

All,

Following the instructions from here:
https://wiki.qt.io/Building_Qt_Documentation

I tried to make the documentation so QtCreator would have it. Yes,  
most people just install the Linux distro version hoping it isn't too  
far away from what they are using, but, I opted to build and install  
the matching doc.

Just passing along and wondering if anyone else had issue building  
docs from everywhere source?
