Displaylink drivers not working (can't install)

Displaylink is a DisplayPort driver used by some Lenovo Docking Stations.

I have one of these Lenovo Docking Stations that relies on Displaylink to use the 4k Monitor connected via DP to my docking station.

The docking station’s USB peripherals (keyb, mouse) all seem to work except for the DP monitor.

In order to be able to use the external monitor via the docking station, I need to install the Displaylink software.

The Displaylink sw vendor only supports Ubuntu but has released info for other parties on how to adapt it to suit their distribution (here: https://support.displaylink.com/knowledgebase/articles/679060-porting-the-displaylink-ubuntu-driver-to-other-lin)

I’ve tried to acquire Displaylink for Ubuntu & followed their instructions to get it to work on Clear Linux 'though I got stuck at libdrm (libdrm seems missing on Clear Linux).

Note: I did follow the instructions & recommendations on this similar topic Displaylink / EVDI in Clear Linux but my issue about libdrm seems to persist.

Here’s the raw output of my 1st attempt at getting Displaylink installed:
