Add tutorial page for CMake template

[ChrisThrasher]

I have no idea how to write PHP, HTML, or do any web development nor do I know how to build these docs to view them locally so bear with me if I did a poor job. I'm mostly copy-pasting from other files that seem to do the thing I want to do.

I ended up repeating most of what is already in the CMake template project's README. I still think we'd be better off simply linking to that project instead of rewriting that project's README into a different language and having to maintain both.

Here's what it currently looks like
