vtk_modules warning in CMake Project

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

  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).
