Programatically set height of collapsingToolbarLayout

Basically, I have a collapsingToolbarLayout with an imageview in the paralax section. This image is guaranteed to be square, and I want to display the whole image, so I need to set the height of the collapsingToolbarLayout to be equal to the width. How can I accomplish this? For some reason wrap_content on the imageView and coordinatorlayout is not making it actually wrap the content. Note that I am using Glide to load the image from a network resource, so I don't have it when the activity starts.

Current Layout:
