Qt decoration plugin implementing Adwaita-like client-side decorations.

This library uses private Qt headers and will likely not be forward nor backward compatible. This library will have to be recompiled with every Qt update. While it can be build using Qt 5, it depends on backported changes from Qt 6. You can get these here.

Build instructions:

mkdir build
cd build
cmake [OPTIONS] [-DUSE_QT6=true] ..
make && make install

It can be used by setting the QT_WAYLAND_DECORATION environment variable:

export QT_WAYLAND_DECORATION=adwaita

The code is under LGPL 2.1 with the "or any later version" clause.
