Hey Mark! I don't really know what I'm doing here. Could you please help me
understand this? I think what this is saying is for a component build, then you
link against the gpu component rather than adding this source to your
compilation unit. Am I right? How do I debug why this existing strategy is
broken? Thanks!

I think you're better off making the source_set below into a component, and
having dependees on :common, instead, depend on your component.

Don't forget to mirror this structure in gyp too.
