Hi all, I have a problem to build OpenCV with Extra Libs.
OS: Win 7 OpenCV: 3.2 Compile: VS2013
After set path of extra modules in OPENCV_EXTRA_MODULES_PATH, click "configure" The error messages are shown and stopped.
*CMake Error at cmake/OpenCVUtils.cmake:1043 (file): file DOWNLOAD cannot open file for write. Call Stack (most recent call first): opencv_contrib/modules/dnn/cmake/OpenCVFindLibProtobuf.cmake:32 (ocv_download) opencv_contrib/modules/dnn/CMakeLists.txt:5 (include)
