So it should not be compiled when compiling digikam 5.x from git then...

Nice guess but this is not what happened : the plugin was compiled  and 
installed from the git tree yesterday.

  cd local/src/digikam/
valette at tri-yann4:~/local/src/digikam$ find . -name kipiplugin_imgur.so
./build/extra/kipi-plugins/imgur/kipiplugin_imgur.so

Could be also resolved at build time if QT5 is selected/detected by 
cmake while it has not been changed to support qt5...

Thanks for the help nevertheless...
