When I configure my project that uses VTK I am consistently getting this error:

````auto
  No `MODULES` passed to `vtk_modules_autoinit`.
Call Stack (most recent call first):
  common/CMakeLists.txt:42 (vtk_module_autoinit)
This warning is for project developers. Use -Wno-dev to suppress it.```

Should I be worried about this?

It means that `vtk_module_autoinit` is being called without any modules to create autoinit bits for. This may mean that there are no modules to deal with (in which case, skip the call completely), or the variable you’re using is empty (which is probably a problem).
