But package qtbase5-dev is installed.

I am using Debian testing/sid

You are mixing new and old Qt versions. See for example:

../../../src/calibre/gui2/pictureflow/pictureflow.cpp:1497:13: error: ‘class QImage’ has no member named ‘setDevicePixelRatio’

IIRC setDevicePixelRatio was added to QImage as of version 5.6 or 5.5

The solution was. I am install the package qt5-default.
