QtE5 for Qt 6

[MGW via Digitalmars-d-announce]

I want to meet Qt 6 by creating QtE6. This forced me to update 
github/QtE5 to the latest stable version: widgetsXX.dll/so + 
qte5.d (qt 5.12.7). Programming is easy, compilation does not 
require Qt metacompiler (it uses a set of ready-made slots), 
works on Linux and Windows. Of course this is not full Qt, but a 
small part that I use every day in my projects.
