Where is this group referenced from?

+  testonly = true  # You shouldn't actually link to this.

[scheib, 2014/09/29 22:37:54]

This code should be linked to non-test targets. Perhaps I'm confused by
'testonly'.

+  visibility = [ "//:*" ]  # Only for the root targets to bring in.

Why?

+
+  deps = [
+    "//extensions/components/native_app_window",
+  ]
+
+  if (!toolkit_views) {
+    deps -= [ "//extensions/components/native_app_window" ]
+  }
+
+}
