Description

## Problem

After installing `cmake`, the Transformer Engine build still fails because NCCL is not installed on the system. NCCL is not listed as a prerequisite in the installation guide.

## Suggested fix

Add NCCL to the prerequisite checklist and document the installation steps (or include it in a convenience install script).
