opencv4.5.5+qt5.15.2+vtk9.1+mingw81_64编译记录
目录
一 VTK编译
二 无opencv_contrib编译记录
三 有opencv_contrib编译记录
四 参考链接
mingw编译器针对很多仓库代码没有编译错误，适配mingw是个好选择。
编译结果文件：
链接：https://pan.baidu.com/s/11pgNAwn_o-saygo1blJz4A
提取码：w5so
一 VTK编译
cd C:\Users\pgjgg\Desktop\CODE\VTKmkdir buildcd buildcmake -DCMAKE_BUILD_TYPE="Release" -G "MinGW Makefiles" -DCMAKE_PREFIX_PATH="C:/Qt/5.15.2/mingw81_64/lib/cmake/Qt5" ../mingw32-make -j48mingw32-make install中间存在编译错误，继续使用编译指令：
mingw32-make -j48
或者在cmake-gui手动取消一些build。
类似这样：
最后管理员运行cmd.exe后，执行：
mingw32-make install
二 无opencv_contrib编译记录
git clone https://gitcode.net/opencv/opencvcd C:\Users\pgjgg\Desktop\CODE\opencvmkdir buildcd buildcmake -DCMAKE_BUILD_TYPE="Release" -G “MinGW Makefiles” -DQT_QMAKE_EXECUTABLE="C:/Qt/Tools/mingw810_64/bin/qmake.exe" -DQt5_DIR="C:/Qt/5.15.2/mingw81_64/lib/cmake/Qt5" -DCMAKE_PREFIX_PATH="C:/Program Files (x86)/VTK/lib/cmake/vtk-9.1" ../mingw32-make -j64mingw32-make install这样是没有适配QT的，需要手动在cmake-gui添加QT。

试了我一个通宵，遇到过一些问题。
比如编译完没有highgui模块。
这个是因为VTK没有带上QT编译。
还有sfm模块编译不了，取消build这个模块即可。
