No support for using an external/system copy of Hedley

[musicinmybrain]

What is the issue you have?

The project uses a bundled copy of Hedley, lightly forked with JSON_ prefixes and with each macro undefined at the end of the header.

It seems like it would be possible, albeit a little tedious, to support including a system copy of hedley.h, “wrapping” the unprefixed macros.

Most Linux distributions, such as Fedora, are opposed to bundling for various reasons. In order to package this software in Fedora, I am required to ask you to support using an external or system copy of Hedley, and to record any response.

Please describe the steps to reproduce the issue.

Look at the sources; see a bundled copy of Hedley.

Can you provide a small but working code example?

And what is the actual behavior instead?

I would not put effort into this myself, but PRs welcome.

Fedora is okay with bundling.
