Bug#1123097: asammdf: FTBFS: dh_auto_test: error: pybuild --test --test-pytest -i python{version} -p 3.13 returned exit code 13

[Gianfranco Costamagna]

Hello Colin, thanks for the explanation and report!

Ideally, PYQTGRAPH_QT_LIB can be exported just to make sure the right backend is used.

However I'm adding the new runtime dependency, to fix tests and reverse-dependencies.

In the future I think upstream will drop qt5 and pyside2, simplifying a lot the dependencies needed.

G.

I traced through this import stack, and pyqtgraph seems to want QtOpenGL 
and QtOpenGLWidgets essentially unconditionally (new as of 0.14.0-1), so 
there seems a decent argument that it should be in Depends.  The 
complication is that which exact packages are needed depends on the 
Python Qt bindings you're using, of which pyqtgraph supports several.

Should asammdf just deal with this with a new Build-Depends (if so, 
please reassign back to src:asammdf), or should something change in 
pyqtgraph?  I don't know this area well enough to make a judgement call.

Thanks,
