Dear Maik, thanks for very quick answer,

Now Digicam is compiled with -DCMAKE_BUILD_TYPE=Debug

You are right, running digikam says:
digikam.general: Parsing plugins from "/opt/qt5/plugins/digikam/"
digikam.general: Plugins found: 0
digikam.general: No plugins loaded. Please check if the plugins were 
installed in the correct path, or if any errors occurred while loading 
plugins.

The directory /opt/qt5/plugins/digikam doesn't exist on my system 
(qt-5.12.7, but it is the same with qt-5.14.1)

I realized that digikam installs its plugins in /usr/lib/plugins/digikam/*
so, I made a symlik : ln -vs /opt/qt5/plugins/digikam -> 
/usr/lib/plugins/digikam
and now all is working well !!

How can I compile digikam so that it searches for plugins in 
/usr/lib/plugins/digikam rather than in /opt/qt5/plugins ?
I don't find anything about this in ccmake ..

Thanks for your help.
Best regards.
Alain
