主要是MSVC需要这些 dll文件 。 可以如下修改CmakeList.txt让它找到
cmake_minimum_required(VERSION 3.12)
project(opencv_test)set(CMAKE_CXX_STANDARD 17)set(CMAKE_PREFIX_PATH C:/Libraries/libtorch-win-shared-with-deps-2.3.0cu118/libtorch)
#set(Torch_DIR E:/libtorch/share/cmake/Torch)
#include_directories(E:/libtorch/include)
#include_directories(E:/libtorch/include/torch/csrc/api/include)
find_package(Torch REQUIRED)

clion编译OpenCV时install的位置在这更多参考 不能用clion编译还是会出现找不到 dll文件的问题
参考如下链接用VS编译
Windows 下使用 CMake Visual Studio 2022 编译 OpenCV 4.8.1 及其扩展模块 主要参考
vs2019编译opencv 注 Opencv_world勾选后后面build可能会出问题不知道怎么解决建议别勾。 之后记得把 D:\prj\opencv\opencv4\out\install\x64-Debug\x64\vc17\bin添加到环境变量。
之后在camke时你可能又出现了问题
CMake Warning at C:/Libraries/opencv-4.8.1/cmake-build-release/install/OpenCVConfig.cmake:190 (message):Found OpenCV Windows Pack but it has no binaries compatible with yourconfiguration.You should manually point CMake variable OpenCV_DIR to your build of OpenCVlibrary.
Call Stack (most recent call first):CMakeLists.txt:8 (find_package)CMake Error at CMakeLists.txt:8 (find_package):Found package configuration file:C:/Libraries/opencv-4.8.1/cmake-build-release/install/OpenCVConfig.cmakebut it set OpenCV_FOUND to FALSE so package OpenCV is considered to beNOT FOUND.这是因为OpenCV_DIR 应当精确到lib 故意的还是不小心的
