Installation/Compilation help needs revamping

[kunaltyagi]

Context

The installation procedures are pretty old and people have to rely on third-party blogs to find reliable instructions.

Expected behavior

The installation steps and details for most of the situations should be available on the website and the PCL repo.

The compilation FAQ also needs to be updated using past reported issues.
