Failing to compile

[josephzsombor]

I am trying to compile this in an Ubuntu/CUDA apptainer using

Bootstrap: docker
From: nvcr.io/nvidia/cuda:12.6.3-cudnn-devel-ubuntu20.04

I have installed all the dependencies, but I keep getting the following error. Do you have any idea what could be causing this? Could it be that there's an issue with my cuda toolkit installation?

  Could not find a package configuration file provided by "CUDAToolkit"
  (requested version 12.0) with any of the following names:

    CUDAToolkitConfig.cmake
    cudatoolkit-config.cmake

  Add the installation prefix of "CUDAToolkit" to CMAKE_PREFIX_PATH or set
  "CUDAToolkit_DIR" to a directory containing one of the above files.  If
  "CUDAToolkit" provides a separate development package or SDK, be sure it
  has been installed.

I installed cuda toolkit as follows:

    wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-keyring_1.1-1_all.deb
    dpkg -i cuda-keyring_1.1-1_all.deb
    apt-get update
    apt-get -y install cuda-toolkit-12-8

Any advice would be appreciated!

I managed to fix the CUDAToolkitConfig.cmake missing issue. It turns out cmake 3.22 is necessary to have FindCUDAToolkit.cmake, so I added the following to my def file:

    # Download the latest CMake installer
    echo "Downloading the latest CMake installer..."
    wget -q https://cmake.org/files/v3.31/cmake-3.31.4-linux-x86_64.sh -O /tmp/cmake.sh
    chmod +x /tmp/cmake.sh
    echo "Installing CMake..."
    /tmp/cmake.sh --skip-license --prefix=/usr/local
    echo "Creating symlink for cmake..."
    ln -s /usr/local/bin/cmake /usr/bin/cmake
    echo "Cleaning up..."
    rm /tmp/cmake.sh
    echo "CMake installation complete."

The version of cmake installed by simply apt-get cmake was < 3.22.

So I can now successfully build Denoiser, but the make command does end with some warnings:
