[Interest] Mac OS X Qt 5 QCoreApplication application crashes if linking with webenginewidgets

My application is not using QtWebEngineWidgets but loading (at run time) a
dylib that links with QtWebEngineWidgets. This external dylib never
instanciates a Web Engine component as the code is not activated when
running headless.

This external dylib can be changed into two libraries for each case and
load only the headless part.

However, the problem starts in a Qt library that creates a OpenGL context
even when it will not be use. Maybe this can be solved too.
