7 years ago I have already solved this problem by myself but there is another issue I just encountered. I followed the instruction of readme.md in document and execute this "cmake -G Xcode -D OpenCV_DIR=$OpenCV_DIR .." and following is the error message:

Does anyone know about this issue, thanks.
I want to use this project to practice for my ios development, but I've never handle this things before:
MacOSX (Xcode): export OpenCV_DIR="~/OpenCV/build" mkdir build cd build cmake -G Xcode -D OpenCV_DIR=$OpenCV_DIR .. open ExploringSfMWithOpenCV.xcodeproj
I've spent my whole day to search this thing "export path...", could someone help me out? My problem is I don't know what is this mean "export OpenCV_DIR="~/OpenCV/build"" and this "cmake -G Xcode -D OpenCV_DIR=$OpenCV_DIR". It's a directory path or something? If you can help me step by step, that will be great.
Thanks Ares
