This issue can handle just the setup of Kapp-ctrl components in Operator-controller's Makefile. More info on the setup:
Here is the dev documentation on the setup that is required to run kapp-controller (to dig further into understanding what happens under the hood).

Direct installation of all the components and controllers can be done using their release manifest:

kubectl deploy -f https://github.com/carvel-dev/kapp-controller/releases/v0.50.0/download/release.yml

Release page for more details:

https://github.com/carvel-dev/kapp-controller/releases/tag/v0.50.0

We haven't still figured out the version compatibility b/w kapp-ctrl and Operator-controller. We can get started with using the latest for now and tackle it accordingly when working on #608.
