Hi,

Thanks for the email. You are right, I do not actually need VTK, just
import memory buffer.
But VTK is already better than the INR format. I saw the code samples
to read VTK objects. My original question was how to enable VTK
support when building. There is no option to control this in the main
CMakeLists.txt.

Many thanks
Dominik
