Create a "Qt Console Application" using QtCreator (4.12.0) wizard.
Try to build and deploy on an Android device.

You'll get the error:

No platform plugin, neither libqtforandroid.so or libqtforandroidGL.so, included in package. Please include one.

With QtCreator 4.8.0 and Qt 5.12, this used to work.

Note that compilation log window reports:

Skipping plugins/platforms/libplugins_platforms_qtforandroid_armeabi-v7a.so due to unmet dependencies: lib/libQt5Gui_armeabi-v7a.so

Adding Qt += gui in pro file fixes the issue, but one may want to deploy an app without QtGui in it.

Any workaround would be appriated.
