Hi,
What you may have heard is that Blink is not designed to be used separately to Chromium in other projects. Rather, it is more appropriate to use the "content" module of Chromium, as that is intended to be plugged into other applications besides the full Chromium browser.
As you can see from the diagram here, WebKit (now Blink) is one component of the "content" module.
(For example the "content_shell" is a demo app that uses content, and you can see that it is a very minimal web browser using the Blink rendering engine.)
I think if you are trying to embed Blink in a separate application, you should be using content and not Blink directly.
