boringssl和openssl不能共存的问题

问题描述：这里在编译arm64-v8a时候遇到问题：boringssl在编译webrtc被依赖，ffmpeg依赖openssl这样会冲突。

1、解决办法：二选一，因为他们接口都一样。没有办法。
用两套如果完全对上版本还好， 但是这个可能性不大。
1.1、都用boringssl编译。
这里重点说下，boringssl编译arm64-v8a问题，直接上贴脚本吧

#!/bin/sh
export ANDROID_NDK=/Users/zhangyf/Library/Android/sdk/ndk/android-ndk-r17c
export ANDROID_HOME=/Users/zhangyf/Library/Android/sdk
$ANDROID_HOME/cmake/3.10.2.4988404/bin/cmake \
    -DANDROID_ABI=arm64-v8a \
    -DCMAKE_MAKE_PROGRAM=$ANDROID_HOME/cmake/3.10.2.4988404/bin/ninja \
    -DANDROID_NATIVE_API_LEVEL=21 \
    -DANDROID_NDK=$ANDROID_NDK \
    -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
    -DCMAKE_BUILD_TYPE=Release \
    -GNinja \
    ../src
cmake --build .

 ffmpeg编译,也是直接上脚本吧。

#!/bin/bash

1.2 另外一种选择：都用openssl 网上有人着么做， owt貌似也是这么做的。
这个我没有试，因为还有别的工程curl也用到boringssl 。
