Build on Linux
Gunship will now be able to find its needed modules (I think) and will build on Ubuntu 14.4.
Unfortunately, it will not run because it still cannot find its plugins.
Also, I think you need to manually specify Gunship's location to cmake if you haven't set the environment variable, but that's because I haven't bothered with a decent find module.
Working Linux Build
closes #15
Gunship + SillyShooter now builds and runs on Ubuntu 14.4.
You still need to manually configure a few options in cmake for the time
being, but it does work.
