Simplified macOS Build Process (#579)

This makes the default xcode project generated by premake work out of the box, and is generally easier for mac users.  Especially those who don't have permissions to modify /Library/Frameworks/

- Look for SDL in RecastDemo/Bin by default rather than /Library/Frameworks/
- Updated README build instructions
- Ignore SDL2.framework in RecastDemo/Bin

 2. The walkable areas described by the mold are divided into simple overlayed 2D regions. The resulting regions have only one non-overlapping contour, which simplifies the final step of the process tremendously.
 3. The navigation polygons are peeled off from the regions by first tracing the boundaries and then simplifying them. The resulting polygons are finally converted to convex polygons which makes them perfect for pathfinding and spatial reasoning about the level.

 ## Detour
 
 Recast is accompanied with Detour, path-finding and spatial reasoning toolkit. You can use any navigation mesh with Detour, but of course the data generated with Recast fits perfectly.
 
 Detour offers simple static navigation mesh which is suitable for many simple cases, as well as tiled navigation mesh which allows you to plug in and out pieces of the mesh. The tiled mesh allows you to create systems where you stream new navigation data in and out as the player progresses the level, or you may regenerate tiles as the world changes. 
 
-## Installation through vcpkg

-If you are using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager you can download and install Recast with a single command:
-```
-vcpkg install recast

 ## Recast Demo
 
 You can find a comprehensive demo project in RecastDemo folder. It is a kitchen sink demo containing all the functionality of the library. If you are new to Recast & Detour, check out [Sample_SoloMesh.cpp](/RecastDemo/Source/Sample_SoloMesh.cpp) to get started with building navmeshes and [NavMeshTesterTool.cpp](/RecastDemo/Source/NavMeshTesterTool.cpp) to see how Detour can be used to find paths.

 It is recommended to add the source directories `DebugUtils`, `Detour`, `DetourCrowd`, `DetourTileCache`, and `Recast` into your own project depending on which parts of the project you need. For example your level building tool could include `DebugUtils`, `Recast`, and `Detour`, and your game runtime could just include `Detour`.
