Cmake

Hi!
I worked on a version more cmake oriented, using the exported targets functionalities. I also added a sketch for cpack, it can be used to generate a deb package, in case you want to add it to canonical ;)

Thanks for the contribution! Much appreciated!

I honestly didn't think it'd be of use to anyone in the package sources, but it seems as though there is a use for it :)
I'll take a gander on how to add it.

One thing I've noticed, is that it doesn't generate a .deb package, rather a series of tar-files. But that may be something on my system. I'll take a further look.

Also, I changed the project name back (removed the lib prefix), because CMake will automatically add the lib prefix, which would result in a file named liblibsockcanpp*.
