[CMake] CMake integration in Gradle (Android Studio)

[Cong Monkey]

My Android Studio Version Info:

Android Studio 2.2.1
Build #AI-145.3330264, built on October 6, 2016

May be the more import part is cmake version, I have two which all works:

~/Android/Sdk/cmake/3.6.3155560
~/Android/Sdk/cmake/3.6.3133135

hope this will be help:)
