Compiling DPC++ for CUDA error

[ranaelnaggar00]

Describe the bug

I am trying to build DPC++ toolchain with support for Nvidea Cuda. I follow the steps here:
https://github.com/intel/llvm/blob/sycl/sycl/doc/GetStartedGuide.md

When I run the following command :

CUDA_LIB_PATH=/usr/local/cuda-12.5/lib64/stubs/ CC=gcc CXX=g++ python3 /sycl_workspace/llvm/buildbot/configure.py --cuda --cmake-opt="
-DCUDA_CUPTI_INCLUDE_DIR=/.local/lib/python3.8/site-packages/nvidia/cuda_cupti/include -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-12.5/ -DCUDA_INCLUDE_DIRS=/usr/local/cuda-12.5/include -DCUDA_CUDART_LIBRARY=/usr/local/cuda-12.5/lib64/libcudart.so"

I get this error:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
~/sycl_workspace/llvm/sycl/plugins/cuda/CUDA_CUPTI_INCLUDE_DIR

There is CMakeCache.txt at ~/sycl_workspace/llvm/build/CMakeCache.txt ... you can try to remove it and rerun.

I have set up these variables as follows:

export PATH=/sycl_workspace/cmake-3.30.0-rc3-linux-x86_64/bin:$PATH

export CUDAToolkit_cupti_LIBRARY=~/.local/lib/python3.8/site-packages/nvidia/cuda_cupti/lib

Would it be possible to help me solve this issue ?

I found that the problem for me was due to the fact that CUPTI was not installed in the path where macros where searching in. So, setting the correct environment variables did not help for me.
So, I modified these to search in directories where the libraries and include folder are located.

macro(find_cuda_cupti_library)

The following if can be removed when FindCUDA -> FindCUDAToolkit

find_library(CUDA_cupti_LIBRARY
NAMES cupti
HINTS /usr/local/cuda-12.5/lib64/
ENV CUDA_PATH
PATH_SUFFIXES /usr/local/cuda-12.5/lib64/ lib64 lib/x64 lib
../extras/CUPTI/lib64/
../extras/CUPTI/lib/
)
endmacro()

macro(find_cuda_cupti_include_dir)
find_path(CUDA_CUPTI_INCLUDE_DIR cupti.h PATHS
"${CUDA_TOOLKIT_ROOT_DIR}/extras/CUPTI/include"
"${CUDA_INCLUDE_DIRS}/../extras/CUPTI/include"
"${CUDA_INCLUDE_DIRS}"
"INCL_DIR"
NO_DEFAULT_PATH)
endmacro()
