I don't have the vtk 8.1 on my system, but with vtk 7.1, there is a flag called *VTK_USE_CXX11_FEATURES*. Try toggling it to ON. You can can search in ccmake using "/", and then typing the string you are looking for. You can try seraching for CXX11. Kind regards. -- Sent from: http://vtk.1045678.n5.nabble.com/VTK-Users-f1224199.html
