--------------------------------------

             Summary: [C++] Cannot build with system CUDA toolkit and conda-forge compilers
                 Key: ARROW-15903
                 URL: https://issues.apache.org/jira/browse/ARROW-15903
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++, GPU
            Reporter: Antoine Pitrou


I have the CUDA toolkit installed on my Ubuntu 20.04 machine. I can build Arrow with CUDA support fine using the system-provided clang. However, if I try the conda-forge clang, I get the following CMake error when configuring:
{code}
-- Unable to find cudart library.
CMake Error at /home/antoine/miniconda3/envs/pyarrow/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
