What does `USE_AUTOLOAD` do?

[hjmallon]

USE_AUTOLOAD=0 is set if USE_SYSTEM_TZ_DB is true and USE_AUTOLOAD=1 otherwise. What is it for? I can't see anything that it is attached to. Is it to do with CURL?

Perhaps some documentation (in README or inline comments) on this and HAS_REMOTE_API would be useful?

At this point you know far more about my CMakeLists.txt than I do. P/R's welcome. :-)

But here's the docs on HAS_REMOTE_API: https://howardhinnant.github.io/date/tz.html#Installation

Maybe @beached knows?

I think that USE_AUTOLOAD changed name to AUTO_DOWNLOAD in recent revisions but cmake was not updated correspondingly, fixing that is part of the PR I just opened: #315
