[Interest] Qt 5.13 QtWebEngine GN Error

[Oliver Niebuhr]

Alright. After constantly running into QTBUG-65677 with too long Path
Names (funny enough reported by me 15 Months ago already, still P2 and
Open. And a lot of other People obviously keep running into this Issue,
so I really hope this will get fixed in Qt 6 as it seems this needs a
bigger build system overhaul which could eat a couple weeks of rewriting
and testing if i read correctly between the lines *FingersCrossed*).


Anyway, after disabling Precompiled Headers for QtWebEngine (as this is
the only Workaround for long Path Names ATM) I am now running into this
Error:

[...]

Question now is: Known Bug? Problem with disabled Precompiled Headers?
Create a Bug Report? Out of Scope because i.e. VS2019 is not officially
supported yet etc.?

Thanks!
Olli
