So I have the lib files. It's failing with only an exit code. No 
window is appearing. It's using the same D code as with the 
dynamic setup which I was able to produce a window with.
```sdl
dependency "bindbc-sdl" version="~>0.1.0"
versions "BindSDL_Static"
subConfigurations "bindbc-sdl" "staticBC"
libs "SDL2" "SDL2_image"
```
