I have win10, visual studio 2017, opencv source & contrib 3.3.0 and cmake 3.9.1. I only unchecked CUDA in configuration step in CMake and after that, I did generate source and opened opencv.sln and tried to build ALL BUILD file. but I got 5 errors and 4 warnings.

How can I fix them? pls!

cmake tries to download a few files(boostdesc_bgm.i, vgg_generated_120.i, a dozen files in all) to build the xfeatures2d module, this failed on your machine. can you take a look at the cmake output or the content of vgg_generated_120.i , there will be messages about it, either a cmake problem, or your box does not allow accessing those files via https
