Features
-------------
* No outside dependencies besides bx, bgfx, and CMake.
* Only tested in Visual Studio 2015 so far.
* Tested on Visual Studio 2015 and Xcode.
* Compiles bgfx, tools & examples.
* Detects shader modifications and automatically rebuilds them (DirectX11 shaders only for now).
* Detects shader modifications and automatically rebuilds them.
* Uses CMake interface libraries (linking against bgfx is one line of cmake code via target_link_libraries).
