Manually building

• Install CUDA 11.4 or newer.
  • Make sure there's an environment variable called CUDA_PATH which is set to the path of your CUDA installation, eg. C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.4
  • If you don't want to set this environment variable, you can change the paths manually in project settings:
    • C/C++ -> General -> Additional Include Directories
    • Linker -> General -> Additional Library Directories
• Open the solution in Visual Studio 2022.
• Set the configuration to Release.
• Build the solution.
