This is to address

Add a function to get lib version #74

Thanks for the pull request!

I added inline comments, can you address them?

Also, you need to add a line in libfreefare/Makefile.am so that make install creates a symlink freefare_version.3 -> freefare.3 (look at linkedman, their are lots a symlinks already created).

I just pushed a few commits to master that should fix the Travis-CI issue you see with CMake.

You can get them in your branch by rebasing. Assuming you have 2 remotes, origin is the "official" repo and broth-itk is your fork:

1. git fetch --all (get all commits locally)
2. git rebase origin/master (add the locally missing commits from origin/master before your local work. Your local commits will be modified, so you will have to use -f to push them next time).

Thanks a lot for your git hints :)
Looks like I managed to get the changes online. Hope it's getting all right

Is there anything to do from my side in order to get this pull request merged?
