To build and run C++ examples/tests you need to instal vtk, vtk-headers, cmake.

To run Tcl, Python or Java examples/tests you need to install vtk and vtk-tcl, 
vtk-python or vtk-java correspondingly.

Remember to set your VTK_DATA_ROOT variable to %%PREFIX%%/share/examples/vtk/VTKData
before running examples/tests.
