After downloading, get a file like opencv_contrib-3.3.1.zip.
C. camke download : https://cmake.org/download/
After downloading, the cmake-3.10.1-win64-x64.zip file is obtained, and cmake-gui.exe in the bin directory can be directly opened and run.
Two, cmake compilation
1. Open the cmake-gui.exe file in the bin directory of cmake that you just downloaded.
2. The first line of cmake is the source code of opencv, which is the source file of opencv, and the second line is the place where the compiled files are placed, which is the mybulid folder.
3. Press Generate for the first compilation, and set the option Visual Studio 12 2013 (if you want to compile to X64 opencv, select Visual Studio 12 2013 Win 64 here), and there will be a sign of done after success.
