    Description

      Qt5.12.0 from qt installer MSVC2017 command Line tools

      python3.7.2, libclang7.0.1  compiled from sources

       

      compiling with :

      python setup.py build --qmake=C:\Qt\5.12.0\msvc2017_64\bin\qmake.exe  --build-tests --ignore-git --verbose-build --relwithdebinfo --reuse-build

       

      *bails out when generating QtGui

       

      This occurs due to CXCursor travers visits itself 

      Suggested fix: (works for me)
