For anyone else looking to embed a modern browser in their Windows/macOS/Linux* C++ application, you might consider Dullahan: source: https://bitbucket.org/lindenlab/dullahan/src/master/ and example screenshot: https://bitbucket.org/lindenlab/dullahan/raw/master/docs/web...

I recently updated it to use Chromium 81 and would have updated it to the most recent version (84) if there weren't some non-trivial changes needed to make video/audio streaming work again.

It's what we use in Second Life and would welcome other users' comments to help improve it.
