Are you using deepstream 1.0?
Could you use latest DS6.0?
deepstream 5.1 im using , have edited the error message could you re-check?
Below is the CMAKE FILE :
CUDA_VER?=
ifeq ($(CUDA_VER),)
$(error “CUDA_VER is not set”)
endif

seems there is no main in your source code, it’s a basic compile problem, it’s should be not related to deepstream.
