I try to enable the vtkDICOM module in VTK 8.2.0, I set the Module vtkDICOM option for the cmake cache:  
cmake -D Module\_vtkDICOM :BOOL=ON …/vtk -source  
then I got the warning:  
**CMake Warning:**  
\*\* Manually-specified variables were not used by the project:\*\*  
\*\* Module\_vtkDICOM\*\*

does anybody know how to handle this?  
thanks
