CMake Error at cmake/OpenCVModule.cmake:370 (_glob_locations): Syntax error in cmake code at …解决办法
这是由于在选择opencv_contrib modules目录时采用复制粘贴，由于配置时文件的地址格式：“C:/Users/Desktop/opencv_contrib-4.3.0/opencv_contrib-4.3.0/modules”,即采用的是“/”，而复制粘贴采用的地址格式是：“C:\Users\Desktop\opencv_contrib-4.3.0\opencv_contrib-4.3.0\modules”是“\”。所以可以将”"修改为“/”即可，或者手动选择目录；
