--------------------------------------
Summary: [C++] CMake cannot find CUDA toolkit
Key: ARROW-16462
URL: https://issues.apache.org/jira/browse/ARROW-16462
Project: Apache Arrow
Issue Type: Bug
Components: C++, GPU
Reporter: Antoine Pitrou
For some reason, after a conda update it seems that CMake is not able to find
the CUDA toolkit anymore:
{code}
-- Unable to find cudart library.
CMake Error at
/home/antoine/miniconda3/envs/pyarrow/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:230
(message):
Could NOT find CUDAToolkit (missing: CUDA_CUDART) (found version
"10.1.243")
Call Stack (most recent call first):
/home/antoine/miniconda3/envs/pyarrow/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:594
(_FPHSA_FAILURE_MESSAGE)

(find_package_handle_standard_args)
src/arrow/gpu/CMakeLists.txt:40 (find_package)
-- Configuring incomplete, errors occurred!
{code}
which is weird as the CUDA toolkit is installed as a Ubuntu package.
