Recently VTK-m was changed to require C++11. The internal builds set properties to require C++11, but these never make it to the configuration for projects that use the VTK-m package (i.e. not declared in VTKmConfig.cmake). This change adds a new CMake target, vtkm, which is an interface. It does not point to an actual library, but it allows code that links it in to have the appropriate compile flags.
