[vtk-developers] VTK forces -std=c++11 ?

[Sean McBride]

Hi all,

In cmake I set CMAKE_CXX_FLAGS to "-std=c++2a" but when I do "make VERBOSE=1" I see that something is passing -std=c++11:

cd /Users/sean/external/VTK-8bin/Common/Core && /Users/sean/llvm/llvm-rel-install/bin/clang++  -DVTK_IN_VTK -DvtkCommonCore_EXPORTS -I/Users/sean/external/VTK-8bin/Common/DataModel -I/Users/sean/external/VTK-8bin/Common/Core -I/Users/sean/external/VTK/Common/Core -I/Users/sean/external/VTK-8bin/Utilities/KWIML -I/Users/sean/external/VTK/Utilities/KWIML -I/Users/sean/external/VTK-8bin/Utilities/KWSys -I/Users/sean/external/VTK/Utilities/KWSys -I/Users/sean/external/VTK-8bin/ThirdParty/utf8 -I/Users/sean/external/VTK/ThirdParty/utf8  -std=c++2a  -g -fPIC -fvisibility=hidden   -std=c++11 -o CMakeFiles/vtkCommonCore.dir/vtkAbstractArray.cxx.o -c /Users/sean/external/VTK/Common/Core/vtkAbstractArray.cxx

Is this a bug?  If not, how do I specify the language variant?

Thanks,
