"#include <cuda/pipeline>" can't be used in multiple src file

hello,I am new to cuda, and there is a compile error which i dont know how to resolve. could anyone help?
I am trying to use 1. Introduction — CUDA C Programming Guide in my code.but compile error.

after some try, i simplify my code, is it a cuda BUG? my code:

// CMakeLists.txt
cmake_minimum_required(VERSION 3.16)
project(cuda-practice_v1 LANGUAGES CXX CUDA)

add_library(all_in_one SHARED ${srcs})
target_include_directories(all_in_one PUBLIC .)
set_target_properties(all_in_one PROPERTIES CUDA_ARCHITECTURES "86")

--- ---

// k.cu

#include <cuda/pipeline>

--- ---

// t.cu

#include <cuda/pipeline>

cmake is not an NVIDIA product. I won’t be able to help much with cmake.

It appears that you are trying to build a .so shared library from two files, each of which has only that include statement. Leaving aside the sense of that., I don’t seem to have any trouble with it:

# cat t.cu
#include <cuda/pipeline>

# cat k.cu
#include <cuda/pipeline>

# nvcc -shared t.cu k.cu -o liball_in_one.so -arch=sm_86
# ls
k.cu  liball_in_one.so  t.cu

CUDA 12.2

cmake has verbose options if you want to see what it is actually doing. I don’t know what it is actually doing here.

thank you for your timely reply.
I try compile without cmake and meet the same error.
cuda 12.2 works for me, thank you again ^.^
