Can you examine your post and see if you can't improve its content. It looks very poor to the point where it can't be followed. — Kolban, Dec 08 '19 at 23:42
you forgot to describe problem in question. Title is not place for this. Downvote. — furas, Dec 09 '19 at 00:46

For that you need to install all the dependencies along with visual studio like Cmake and all.

Let me share the proper document for installation
