Proposition of a different packaging for this project

[matlo607]

Hi,

Recently, I have been struggling to use your project http-link-header-cpp. I was initially trying to build jsonld-cpp into conan and faced those following issues:

• header path missing the project name directory, so possible clashes
• some copy-pasted dependencies inside the project. (uriparser, doctest)
• the cmake script has assumptions about how the dependencies are exposed which makes the export of the artifacts difficult in a package manager (not necessarily conan).

I added instructions in the README for the new proposed workflow.
Please could you have a look at this PR and let me know if you agree on the direction?

Thank you for the PR! I'm excited to check it out. I'll get back to you as soon as I can.

PS: I am preparing a similar PR for json-cpp. It might be better if you see how it works all together. I will probably publish the PR in a few hours.

Edit: danpape/jsonld-cpp#16

While we're not interested in switching to Conan, we'll take a look at how to make our project dependencies more compatible with your package manager toolset.
