where to find CMAKE_OSX_SYSROOT in IOS
<p>i am trying to install opencv on my Mac IOS and there is this step of Adding an SDK path to <code>CMAKE_OSX_SYSROOT</code>, it will look something like this <code>/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk</code>.
and Add <code>x86_64</code> to <code>CMAKE_OSX_ARCHITECTURES</code>, but don't know how to do it</p>
