Linux quick start guide

1. Fork necessary repositories:
   • Engine at https://github.com/KNTGPolygon/PolyEngine
   • Example projects at https://github.com/KNTGPolygon/PolyEngineExamples
2. Clone those repositories to your Linux machine
3. Install required packages:
   • Tools: apt install git make cmake python3 python3-pip clang-5.0 g++-8 gcc-8
   • Engine dependancies: apt install mesa-common-dev libgl1-mesa-dev qt5-default
   • Python modules: pip3 install gitpython
4. Use InitializeSubmodules.py script to initialize all submodules, update them and apply our patches.
5. Use ProjectTool.py script to create makefile files for game project or just for engine (-p option). That's it.
