Possible to install by linking from kustomize?

Describe the solution you'd like

From the installation instructions, it looks like installing this involves cloning this repo and running make install.

Is it possible instead to include a path like https://github.com/ContainerSolutions/externalsecret-operator/tree/master/config/crd in a kustomization.yaml as a resource, rather than running any commands locally?

What is the added value?

To the extent it's even possible — simpler, less dependent on local machine's state.

Thanks in advance!
