OpenCV ANDROID_ABI: not all variants are displayed
<p>I downloaded OpenCV 2.4.13 release from <a href="https://github.com/Itseez/opencv/releases/tag/2.4.13" rel="noreferrer">GitHub</a>. Then I configured CMake project using CMake-gui for android. </p>

<p>There is variable called ANDROID_ABI and I can select value for it using drop-down list. But in this list I can chose only armeabi, armeabi-v6 with VFP, armeabi-v7a, armeabi-v7a with NEON, armeabi-v7a with VFPV3.</p>

<p>I can use CMake console for configure and generate project for arm64 or I can modify cmake scripts and list it manually. But when I try to build generated project, I get error <code>unknown type name '__uint128_t'__uint128_t</code>. So I think there are reasons why I can't select this variant from drop-down list.</p>

<p>How can I chose arm64 variant for build and why I get such kind of error?</p>
