Try building it like this instead:

Here is a workaround solution to fix the issue:

<ol>
<li>Download MACOSX SDK <a href="https://codeload.github.com/phracker/MacOSX-SDKs/zip/MacOSX10.11.sdk" rel="nofollow noreferrer">here</a>.</li>
<li>extract head files from <code>MacOSX10.11.sdk/MacOSX10.11.sdk/System/Library/Frameworks/QTKit.framework/Headers/</code></li>
<li>Create a folder under opencv source file folder: <code>opencv-3.2.0/modules/highgui/src/QTKit</code>, and copy all header files into the folder.</li>
<li>Follow the regular opencv build steps. When you run make -j8, you don't need set <code>"-DWITH_QUICKTIME=OFF -DWITH_GSTREAMER=OFF -DWITH_FFMPEG=OFF"</code> </li>
</ol>

This works for opencv2.x and 3.x

This error is because of QuickTime Kit was deprecated in OS X v10.9,and Apple suggest to use AVFoundation framework instead <a href="https://developer.apple.com/reference/qtkit#overview" rel="nofollow noreferrer">Apple API Reference</a>.

OpenCV (version 3.1.0) is relaying on QuickTime Kit.
So, when you trying to install OpenCV (before version 3.1.0) on OSX Sierra, It will raise error when you make. 

Try install the master version of opencv will be OK !

OpenCV had AVFoundation Framework supported in <a href="https://github.com/opencv/opencv/pull/7159" rel="nofollow noreferrer">https://github.com/opencv/opencv/pull/7159</a>

use <code>--with-quicktime</code> or <code>-DWITH_QUICKTIME=TRUE</code>. It will use QUITCKTIME Instead of QTKit for Video I/O
