Fix RFC links and MSVC build issues

[YATIN072007]

Updated the broken RFC links in the docs (fixes #189).

Also made small changes in src/CMakeLists.txt to fix the build on Windows/MSVC by adding NASM detection and adjusting some compiler problems/complications .

Kindly review...

PR #246 suggests this PR should not be landed.

I haven't reviewed any of it yet, but PR for a PR that hasn't landed suggests we should land this.

Fixed the key leak issue which was generated in the first two commits, kindly review

Hey @YATIN072007 - looks like this PR has some bleed-through from #243. I’m seeing changes related to making examples self-contained/runnable, which isn’t part of this issue.

Could you split those into a PR #243 and revert them here so we can land this one quickly?
