[vtkusers] VTK updated to CMake 3.3 and C++11

[Carlos Lopez]

Hi,

The C++11 check is failing for me. I'm using CMAKE 3.6.2 on windows with
Visual studio Community 15.

Removing the check within cmake allows me to build without issues.

I'm building from gitlab's main repo, updated today.

best,
carlos
