直接用msys2的opencv（推荐）
pacman -S mingw-w64-ucrt-x86_64-opencv CGO_CXXFLAGS=--std=c++11 CGO_CPPFLAGS="-ID:\sdk\msys64\ucrt64\include\opencv4" CGO_LDFLAGS="-LD:\sdk\msys64\ucrt64\lib -lopencv_core -lopencv_photo -lopencv_face -lopencv_videoio -lopencv_imgproc -lopencv_highgui -lopencv_imgcodecs -lopencv_objdetect -lopencv_features2d -lopencv_video -lopencv_dnn -lopencv_xfeatures2d -lopencv_plot -lopencv_tracking -lopencv_img_hash -lopencv_calib3d" go build -tags customenv gocv.go
编译出来执行报错
gocv.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
安装opencv时候的提示
可选的依赖 #(mingw-w64-ucrt-x86_64-qt6-5compat (for the HighGUI module) #mingw-w64-ucrt-x86_64-vtk (opencv_viz module)) ? 最后确认,少的库就是mingw-w64-ucrt-x86_64-qt6-5compat,安装即可,安装另一个也可能能用

从源码自己编译
(推荐)直接用msys2的ucrt64(ucrt) gcc 编译 or 下载 https://github.com/niXman/mingw-builds-binaries/releases posix-seh-ucrt-rt_v10 或者mingw64(msvcrt) gcc 编译 or 下载 https://github.com/niXman/mingw-builds-binaries/releases posix-seh-msvcrt-rt_v11 执行build.cmd CGO_CXXFLAGS=--std=c++11 CGO_CPPFLAGS="-ID:/sdk/opencv/build/install/include" CGO_LDFLAGS="-LD:/sdk/opencv/build/install/x64/mingw/bin -lopencv_core4100 -lopencv_photo4100 -lopencv_face4100 -lopencv_videoio4100 -lopencv_imgproc4100 -lopencv_highgui4100 -lopencv_imgcodecs4100 -lopencv_objdetect4100 -lopencv_features2d4100 -lopencv_video4100 -lopencv_dnn4100 -lopencv_xfeatures2d4100 -lopencv_plot4100 -lopencv_tracking4100 -lopencv_img_hash4100 -lopencv_calib3d4100 -lopencv_bgsegm4100 -lopencv_aruco4100 -lopencv_wechat_qrcode4100 -lopencv_ximgproc4100" go build -tags customenv -o D:/sdk/opencv/build/install/x64/mingw/bin/gocv.exe gocv.go

自己写tag写cgo不可用，可能是因为gocv是第三方包，无法透传?
跨包的#cgo应该不会生效,不然gocv也不会在子包cuda再写一遍了
