By not providing “FindCUDA.cmake“ in CMAKE_MODULE_PATH this project has asked CMake to find a pack

编译错误：

CMake Error at CMakeLists.txt:23 (find_package):
By not providing "FindCUDA.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CUDA", but
  CMake did not find one.

  Could not find a package configuration file provided by "CUDA" with any of
  the following names:

    CUDAConfig.cmake
    cuda-config.cmake

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

cuda
问题分析找不到cl.exe

原因：我用的mingw，而不是msvc的编译工具。
解决方案：二选一

1. 编译工具选择msvc（推荐）
2. 找到cl.exe添加到环境变量中（这种晚上一搜就有方案）

分析

cmake 3.27版本开始
find_package(CUDA)已经弃用了
我们采用下面这种方法
CMakeLists.txt

project(FaceDetect LANGUAGES CXX CUDA)

或者，使用enable_language(CUDA)

方案一：编译工具选择MSVC

我用的clion
打开设置，找到visual studio 移动到到顶上，点确认
