QtQuick module (and the upcoming Qt3D module) require OpenGL 2.0 or higher: the DLLs you've seen help in providing that functionality. Qt can use native OpenGL from your system, or indirectly (through Angle project, so leveraging the DirectX drivers).

QtCore does not depend on OpenGL. QtGui module might depend on it (the dependency can be dropped when OpenGL is disabled in Qt configuration flags - but that can only be done when compiling Qt from source).
