Building artoolkitx-calibration on iOS

Hi folks

I don't manage to build artoolkitx-calibration for iOS using XCode 9.3 on macOS 10.13.3.

Downloading the SDK from https://github.com/artoolkitx/artoolkit ... /download/ went fine by following the steps in build.sh.

I found, downloaded and linked binaries for the opencv2.framework on SourceForge: https://sourceforge.net/projects/opencv ... pencv-ios/

I updated the signing section of the Xcode target "artoolkitX Camera Calibration Utility" so that Xcode will be able to deploy the app to my iPhone.

However, the app doesn't compile yet. In prefs.hpp, the line 61:

cv::Size getPreferencesCalibrationPatternSize(void *preferences);

fails with the error:

'getPreferencesCalibrationPatternSize' has C-linkage specified, but returns user-defined type 'cv::Size' (aka 'Size_<int>') which is incompatible with C

Any pointer to bring me one step further in compiling this app would be greatly appreciated.

Cheers
Pierre
