Dependencies To Install:

• Install the latest Boost (currently 1.60.0_2), via command:

    brew update
    brew install boost
  

• To Make sure Boost 1.60.0_2 is installed, we want to check if the following directory exists via command:

    /usr/local/Cellar/boost/1.60.0_2/include/
    Expected result: /usr/local/Cellar/boost/1.60.0_2/include/: is a directory
  

• Install SDL2:

    1. Go to the website: https://www.libsdl.org/download-2.0.php 
    2. Download runtime binaries and extract them.
    3. Drag the .framework and drop it into directory: /Library/Frameworks 
    4. cd into SDL2.framework
    5. Sign the framework via command: codesign -f -s - SDL2
    6. Link SDL2.framework in GameEngine.xcodeproj under Link binary with libraries
  

• Install SDL2 Mixer:

    1. Go to the website: https://www.libsdl.org/projects/SDL_mixer/
    2. Download runtime binaries and extract them.
    3. Drag the .framework and drop it into directory: /Library/Frameworks

• Link Freetype2 in Xcode:

    Since the header seach path is configured already, you'll just have to:
    1. Find libfreetype.dylib in either: /usr/X11/lib/libfreetype.6.dylib or /opt/X11/lib/libfreetype.dylib
    2. Drag libfreetype.dylib or libfreetype.6.dylib into Link binary with libraries section in GameEngine.xcodeproj 
  

Compile and Run:

To configure and run on xcode: edit scheme -> Options -> check 'Use custome working directory' and point to the directory containing all the source code. Then the project should run without any problems.
