[vtk-developers] VTK Examples don't build properly on Mac, CMAKE_OSX_ARCHITECTURES issue

[Bill Lorensen]

Sean,

Yes,

The examples are built with a custom command. This facilitates
building an example directory from a VTK build or individually. I
discovered this as I added more example.

Look in VTK/Examples/CMakeLists.txt. You will see a custom command
that runs CMake on the examples. It passes vtk build options to the
custom command. The weakness here is that not all cmake options are
passed. You found one. I assume there are more. Try adding your
CMAKE_OSX_ARCHITECTURES.

Bill
