CMake疑難雜症

Failed to detect a default CUDA architecture或是CMAKE_CUDA_ARCHITECTURES must be non-empty if set

直接告訴CMake nvcc的位置，注意舊的build資料夾要先清掉
-DCMAKE_CUDA_COMPILER=/usr/local/cuda-11.7/bin/nvcc

VS code設定cmake的環境變數

在setting.json加入"cmake.environment": {"CUDA_VER":"11.7"}，說明書:https://github.com/microsoft/vscode-cmake-tools/blob/main/docs/cmake-presets.md#ignored-settings

CMake 系統環境變數設置

libcuda.so.1 not found

使用find_package(CUDAToolkit)並且在target_link_libraries 加入CUDA::cuda_driver

CMake find_package() 用法

CMake有許多尋找套件的module，例如FindCUDAToolkit，下面連結條列各種find_package()能使用的module
