compilation issue Ubuntu 18.04

System: Ubuntu 18.04 Cuda: 11.2 Qt: 5.10.1 GPU: RTX 3090

I am building the project in Qt for the first time and I am getting the following error: "/usr/bin/ld cannot find -lcuda" as seen in the picture below:

Additionally, in qtcreator terminal, I'm getting the following error message:

I can see that it's not able to locate cuda. But based on the messages it looks like it get can find cudart but not cuda. Any thoughts? Been struggling with this for a while... also I'm pretty certain cuda is properly installed as well.

Hello, I've never had this problem before, so I'm not sure how to solve it, but have you performed the mandatory post-installation actions mentioned in the cuda installation guide for Linux? Are you able to build the cuda samples without error?
