#find opencv lib
find_package(OpenCV REQUIRED
NO_MODULE # should be optional, tells CMake to use config mode

NO_DEFAULT_PATH) # and don't look anywhere else
cmakelist设置方法ok
2.windows，linux通用：测试ok
set (OpenCV_DIR E:/opencv/opencv)
#opencv
find_package(OpenCV REQUIRED)
注意1：下划线为右下划线：
SET(OpenCV_DIR F:/opencv4.5.4/opencv/build)
注意2:
You might need to add F:\opencv4.5.4\opencv\build\x64\vc15\bin to your PATH to be able to run your applications.
注意3:
cmake编译依赖的opencv需要有文件：
OpenCVConfig.cmake
环境变量设置方法ok
环境变量设置：
OpenCV_ROOT 值 D:\opencv340
OpenCV_DIR 值 D:\opencv340
cmakelist.txt中，
错误写法：
if (WIN32)
find_package(OpenCV REQUIRED PATHS ${OPENCV_DIR}/build/ NO_DEFAULT_PATH)
正确写法：
if (WIN32)
find_package(OpenCV REQUIRED)
