[Qtwebengine] Qt5WebengineCore pdbs are built without source information

[Tassilo Glander]

Hi,
it appears that when building QtWebengine (Windows, Visual Studio 2015 SP2), that the PDBs of Qt5WebEngineCored.dll do not contain source information. That is, I get a working call stack including the functions called, but cannot see the exact line and source file. 
However, I have no issues with other Qt dlls, like Qt5WebEngineWidgetsd.dll.

Is this on purpose? Is there a way to activate the inclusion of source information on WebEngineCore as well?

Thanks,
Tassilo
