You also need to modify the associated BUILD.gn file.

[dougarnett, 2016/04/28 00:18:03]

Do we need to add all our files to it then in new target then? 
The local BUILD.gn only has a proto defn currently.

[Pete Williamson, 2016/04/28 00:28:45]

Yes, we may need to add a new target.  If we do add a new target, we'll need to
modify a higher level BUILD.gn file to include our target.  See my latest issue
1914333002 for an example of what to change in a higher level build file.
