Windows静态编译Opencv

同样Windows端也需要进行Opencv的静态编译，和MacOS的逻辑类似，只是有些许不同

1. 下载Opencv


wget -O opencv.zip https://github.com/opencv/opencv/archive/refs/tags/4.11.0.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/refs/tags/4.11.0.zip
unzip opencv.zip
unzip opencv_contrib.zip

创建build文件夹，后续构建的Opencv将先保存到这个位置


mkdir build
cd build

2. 安装vcpkg 并安装Opencv 依赖库


git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat


.\vcpkg.exe install libpng:x64-windows-static libjpeg-turbo:x64-windows-static tiff:x64-windows-static openblas:x64-windows-static-release

3. 编译 Opencv

回到上一级目录，并进入build 文件夹中。

这里需要指定一下DCMAKE_INSTALL_PREFIX opencv的安装地址，还有vcpkg的cmake地址：DCMAKE_TOOLCHAIN_FILE（在刚刚clone vcpkg的目录下）。


cmake `
    -DCMAKE_BUILD_TYPE=Release `
    -DBUILD_SHARED_LIBS=OFF `
    -DWITH_OPENBLAS=ON `
    -DWITH_ACCELERATE=OFF `
    -DWITH_TEGRA=OFF `
    -DCMAKE_INSTALL_PREFIX="F:/opencv/install" `
    -DBUILD_DOCS=OFF `
    -DBUILD_EXAMPLES=OFF `
    -DBUILD_TESTS=OFF `
    -DBUILD_PERF_TESTS=OFF `
    -DWITH_PNG=ON `
    -DWITH_JPEG=ON `
    -DWITH_TIFF=ON `
    -DWITH_WEBP=OFF `
    -DWITH_OPENJPEG=OFF `
    -DWITH_JASPER=OFF `
    -DWITH_OPENEXR=OFF `
    -DWITH_V4L=OFF `
    -DWITH_FFMPEG=OFF `
    -DWITH_PROTOBUF=ON `
    -DWITH_IPP=OFF `
    -DWITH_OPENCL=OFF `
    -DWITH_CAROTENE=OFF `
    -DBUILD_opencv_java=OFF `
    -DBUILD_opencv_python=OFF `
    -DCMAKE_TOOLCHAIN_FILE="F:/rust/vcpkg/scripts/buildsystems/vcpkg.cmake" `
    -DOPENCV_EXTRA_MODULES_PATH="../opencv_contrib-4.11.0/modules" `
    ../opencv-4.11.0

编译并安装


cmake --build . --target install --config Release --parallel 8
cmake --install . --prefix F:/opencv/install

4. 构建自己的应用

指定一下环境变量


$env:OPENCV_LINK_LIBS="opencv_core4110,opencv_imgcodecs4110,opencv_imgproc4110,opencv_dnn4110,ittnotify,zlib,libjpeg,libpng,libtiff,libprotobuf"
$env:OPENCV_LINK_PATHS="F:/opencv/install/x64/vc17/staticlib"
$env:OPENCV_INCLUDE_PATHS="F:/opencv/install/include"
$env:OPENCV_MSVC_CRT="static"

构建自己的应用


cargo build --release
