Can VTK-m be used without CMake?

Currently, when trying to use VTKm without CMake, we obtain an error:

$ g++-9 -I/usr/local/include/vtkm-1.4 Foo.cxx
In file included from /usr/local/include/vtkm-1.4/vtkm/cont/Serialization.h:15,

(In this case Foo.cxx was simply the file vtk-m/examples/tetrahedra/Triangulate.cxx taken out of it's natural habitat.)
