Доброго дня! Пытаюсь собрать OpenCV для Qt(5.4.2) под win10 x64. Алгоритм сборки смотрел здесь
https://www.youtube.com/watch?v=csxkdGQQgNg и здесь
http://recog.ru/blog/opencv/4.html и где только не смотрел.. пробовал разные версии OpenCV и CMake. Из последних opencv-3.1.0, CMake-3.6.0-rc2-win64-x64 и везде на этапе mingw32-make получаю ошибку связанную с zlib (см. аттач).
На этапе конфигурирования CMake есть warning :
CMake Warning (dev) in modules/highgui/CMakeLists.txt:

target on Windows. Run "cmake --help-policy CMP0020" for policy details.
Use the cmake_policy command to set the policy and suppress this warning.
This warning is for project developers. Use -Wno-dev to suppress it.
