Build fails on Ubuntu 16.10

Hello, I just tried building medusa (master branch) and got this error:

It would seem that tar xfz can't unzip the hunter-5.5.1-cvpixelbuffer-2.7z archive, 7z x however unzips it just fine. Any idea of why that happens or how I can circumvent this?

Thanks for your help.

Hi Talanor,

It seems this error occurs because you're using an old version of CMake. Please try to upgrade to the latest and try again. BTW, it might require some packages. Since I don't really use Ubuntu, I don't remember which ones, but pkg-config and libqt5opengl5-dev are mandatory (cf. https://github.com/wisk/medusa/pull/57/files). Finally, people reported me I might have broken the UNIX build. If you've trouble to compile it, please reset to this commit. I'll try to fix ASAP, sorry for the inconvenience.
