Cake can't find nvcc. CUDAToolkit_ROOT environment variable must be set. Ubuntu/Pop_OS 21.10

Hello!

Please delete the CUDAToolkit_ROOT enviroment variable, add /usr/local/cuda-<version>/bin to PATH in the /etc/environment configuration file and restart the machine (see https://www.jetbrains.com/help/clion/cuda-projects.html#set-nvcc). Does it help?

Hello

I have done as you said, but cuda does not install to usr/local/ in Pop!_OS, like vanilla ubuntu, so instead of usr/local/cuda-<version>/bin, I edited the path variable to usr/lib/cuda-<version>/bin

As such my environment looks like:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/cuda-11.2/bin"

with cuda-11.2 variable at the end. I rebooted, started a brand new Clion cuda executable, and got the same exact error message

Could you please try setting the CMAKE_CUDA_COMPILER variable to the location of the NVCC executable in File | Settings | Build, Execution, Deployment | CMake? See the second point here https://www.jetbrains.com/help/clion/cuda-projects.html#set-nvcc

Hello I have done as instructed. I get the same error. This is my setup. I tried with and without " ":

I can compile fine doing a manual cmake and running make in the terminal so I know it's not cmake's problem. This is what my cuda paths look like:

Please send the following materials to clion-support at jetbrains.com:

1. Do Help | Collect Logs and Diagnostic Data and send us the resulted archive. Note that logs might contain private user's information (like file paths and names).
2. Do Tools | CMake | Reset Cache and Reload Project and send us the entire output from the CMake tool window.
3. CMakeOutput.log and CMakeError.log if you have them in `<project>/cmake-build-debug/CMakeFiles`
4. The output of executing CMake in Terminal.
