The error is:

Unresolvable dependencies to package bindbc-loader:
   bindbc-sdl 0.19.1 depends on bindbc-loader ~>0.3.0
   bindbc-sdl 0.19.1 depends on bindbc-loader ~>0.3.0
   bindbc-wgpu 0.1.0-alpha8 depends on bindbc-loader ~>0.2.1

What is the cleanest way to resolve this? I don't understand why 
can't -sdl and -wgpu use different versions of the loader library.

You can't use different versions of a library in the same library 
in the same program because library version isn't included in 
name mangling, so you'll get link errors for having multiple 
definitions of the same symbol.

Ahh ok, that makes sense. I patched bindbc-wgpu locally to use 
loader ~>0.3.0 and it's working now.
