add installation directives to cmakelists.txt

Cylix commented 6 years ago

This change addresses #297.

@thibault-martinez this will only install iota.lib.cpp includes and library, and the tests binary if they were built. Do you think we should also install dependencies such as cpr / json / curl?

I think there are two things we may need to consider:

we do include some libraries in our header files, thus json headers need to be somewhere in the path when building our library.
curl provides a shared library which is loaded at runtime, so we may need to install it such that it is in the installation path as well.
installing those may conflict with previously installed libraries.

Do you have any particular opinion on this? I would be fine with installing those deps as well.

@Cylix Same here, please rebase

Rebased here as well, CI in progress

Not sure why, on appveyor it built IRI 1.5.0 but with the old .appveyor config file. I rebased master, hopefully should be good.
