编译puffer

安装依赖libmpeg2-4-dev, libopus-dev, libsndfile1-dev, libavformat-dev, libpq-dev, libpqxx-dev, libyaml-cpp-dev, libcrypto++-dev, liba52-0.7.4-dev, libtorch-dev 。

把src/media_server/Makefile.am里链接mkldnn的flag给去掉，因为libtorch_cpu.so会自动链接libdnn，这个flag是完全多余的，不去掉还会报找不到mkldnn库的错。

diff --git a/src/media-server/Makefile.am b/src/media-server/Makefile.am

现在可以开始编译了，

./autogen.sh
./configure
make -j4 CXXFLAGS='-DNONSECURE'

是否添加这个NONSECURE的宏完全看自己是否乐意去折腾ssl证书。
