I'm not sure if we should have these as .sh scripts. Although I think its good information to capture, I get nervous if someone says "just run this mystery script" ...

For one, it is missing the !# at the start, but also it doesn't handle any errors, e.g. if the "mkdir" or "cd" fails, then you'll end up running cmake in the wrong dir. Or something.

Instead of giving a script that is directly in script form -- my recommendation would be to add this to the README, and let the user put it (e.g. copy/paste) into their own script file. This is safer, as it doesn't make assumptions about the user's system, and the onus is on the user to make sure its correct for their system before they go and run it.

Thank you for your review comments, Joe. I agree with all of them. This PR is ready to close. Mostly my intention was to document scripts that I shared with another team member.
