This is my firs use of opencv_extra , cant found something about building in vs . Trying to build program with "text" module from opencv_extra. I was added headers from include in text module to my opencv include folder, but it's only headers and I have errors like " unresolved external symbol "struct cv::Ptr<class cv::text::erfilter="">" so where I can get text.lib ? Or I must do something else for build programs with extra modules ?
