==== Building example-common (debug) ====
vertexfilter.cpp
../../../3rdparty/meshoptimizer/src/vertexfilter.cpp:171:9: error: use of
      undeclared identifier '__builtin_rotateleft64'
        return __builtin_rotateleft64(v, x);
......

How to resolve ?
modify vertexfilter.cpp. just 'return (v << (x & 63)) | (v >> ((64 - x) & 63));' directly.

run example

• 1, copy libs from 'bgfx.build\android-arm64\bin' to 'bgfx-android-activity\app\src\main\jniLibs\arm64-v8a'
• 2, then run app
