Describe the bug
when I use cmake to build the example, It raise:
-- CPM: Adding package cuco@ (dev)
-- CPM: cuco: Using local package Thrust@1.17.2.0
-- CPM: cuco: Adding package libcudacxx@2.1.0 (2.1.0)

and then I compile:

How to fix it?
### How to Reproduce
just cmake ..
### Expected behavior
It can be compile correctly.
### Reproduction link
_No response_
### Operating System
Ubuntu Linux 20.04 and nvcr.io/nvidia/nvhpc:23.9-devel-cuda_multi-ubuntu20.04
### nvidia-smi output
I use nvidia official docker container with nvidia Hpc Sdk 23.9 ,so the CUDA Version is not same with nvcc.

Thanks for reporting the issue.
There was a relevant discussion here #391. Essentially, our code relies on relaxed lambda and constexpr expressions thus building with --expt-extended-lambda --expt-relaxed-constexpr options is necessary.
Thanks! It can be compiled now.but the cmake build error still exists. So It means this error can be ignore?
Yes, those are falsely flagged as errors it seems. I'll ping the maintainers of our build ecosystem to see if we can get this resolved. Meanwhile I opened #398 which now prints a hint about which compiler flags are missing during build.
Resolved.
