is this necessary with the mapping in GypBinaryTargetWriter::WriteType?

[brettw, 2013/10/15 21:18:06]

I was concerned about the following case: The gn target depends on base
(component). In GYP base is a shared library and in GN its a source set.

If base is marked external and the gn target isn't, then we'll get a
gn-generated gn target depending on the gyp-generated base target. But since gn
thinks base is a source set, it will pull the files in directly and I think it
won't work.

So if we have GN->GYP dependencies, the component mode has to match between the
two builds.
