Build Deps on Ubuntu

These are the packages I needed to install for it to build.

• libglib2.0-dev
• libgl-dev
• libxcursor-dev
• libatk1.0-dev
• libgtk-3-dev
• libxcb1-dev
• libxcb-icccm4-dev
• libxcb-dri2-0-dev
• libx11-xcb-dev

So:

sudo apt-get install -y libglib2.0-dev libgl-dev libxcursor-dev libatk1.0-dev libgtk-3-dev libxcb1-dev libxcb-icccm4-dev libxcb-dri2-0-dev libx11-xcb-dev
