Example broken SetPerspectiveCamera not defined

[ynnob]

The following example code does not work. SetPerspectiveCamera is not defined.

"ViewPointBuilder" does not contain a definition for "SetPerspectiveCamera", and no accessible extension method "SetPerspectiveCamera" accepting a first argument of type "ViewPointBuilder" could be found (are you missing a using directive or an assembly reference?).

using BcfToolkit.Builder.Bcf30;

            var builder = new BcfBuilder();
            var bcf = builder

                .SetTitle("Simple title")
