Please use labels and text to provide additional information.

This was likely broken by https://crrev.com/4dafc60789. The problem is that assets_loader.cc (in the vr_base target) includes vr_features.h (generated by the vr_build_features target) without the vr_base target depending on the vr_build_features target.
