While Tobias correctly points out that 11.x is not really on our (KDE@) 
support-list anymore even if it is supported by the FreeBSD project, the

Here you are mixing Qt 5.14 and Qt 5.15, and *that* is definitely not 
supported. This happens when building ports in a dirty environment, or with 
some tools that don't update parts in the right order. We generally recommend 
building with poudriere, because that *does* do things cleanly.

(Getting Qt and KDE to build while an existing version is installed is really 
tricky, since you need *some* -I /usr/local/include to get other dependencies, 
but as soon as you do that you run the risk of also getting the old-installed 
Qt and KDE headers as well -- so best to do it cleanly)
