Make CV-CUDA buildable for Jetson

JanuszL · JanuszL · commit 333ab8dc0259 · 2023-08-03T20:35:21.000+02:00
- libcudart on Jetson (CUDA 11.8) requires shm_open symbol which
  is provided by librt, without it linker complains about a missing
  symbol. This PR makes sure that whenever libcudart is linked -lrt
  linker flag is added as well
