I see this duplicated many times in all the targets. Is there a way to share?

[Dirk Pranke, 2015/10/28 22:55:35]

You could probably create a template that wrapped source_set() and did 
the appropriate adjustments, but I'm not sure if it would be an overall 
win. It might be worth trying.

I'm not sure that there are any other easy alternatives.

[U. Artie Eoff, 2015/10/28 22:57:31]

I could not figure out how to share it in GN

[U. Artie Eoff, 2015/10/28 22:59:59]

I could not figure out how to get templates to work for this... I tried.

[Dirk Pranke, 2015/10/28 23:05:30]

Hmm. I think you should be able to get something to work.

Maybe land this as-is and we can see if we can get something working in a
follow-up CL?
