Bug#1041300: qt6-base-dev: undeclared file conflict with libqt6opengl6-dev

[Helmut Grohne]

Package: qt6-base-dev
Version: 6.4.2+dfsg-12
Severity: serious

The recent upload makes qt6-base-dev include a fair number of files also
contained in libqt6opengl6-dev. Is this some kind of packaging mistake?
