Problem installing paraview 5.6.1

Hi there. I have downloaded paraview-5.6.1 from this website and I install it using the guide in the link I have done all the steps, but when I input paraview in the terminal, I got Segmentation fault (core dumped). For your information, I am using ubuntu 18.04LTS. The reason I download paraview-5.6.1 is to use NVIDIA IndeX which it is not bundled in paraview-5.6. May I know where can I get the installation guide to install?

Thank you.

The ubuntu provided package does not contain NVIDIA index.
