-The Visualization Toolkit (VTK) is an open source, freely available
-software system for 3D computer graphics, modeling, image processing,
-volume rendering, scientific visualization and information
-visualization. VTK also includes ancillary support for 3D interaction
-widgets, two and three-dimensional annotation, and parallel
-computing. At its core VTK is implemented as a C++ toolkit, requiring
-users to build applications by combining various objects into an
-application. The system also supports automated wrapping of the C++
-core into Python, Java and Tcl, so that VTK applications may also be
-written using these interpreted programming languages.

-VTK provides several language bindings. You may need to modify related
-cmake options. Only Qt binding is enabled by default.
+You can enable a lot of optional features by passing variables to the script
