解决办法：
1.先到/usr下面搜索一下这个文件，我在/usr下面搜到了有
/usr/lib/aarch64-linux-gnu/libsndfile.so.1.0.31
/usr/lib/aarch64-linux-gnu/libsndfile.so.1

 find /usr -name "libsndfile.so*"

2.编辑rknn_model_zoo-main/3rdparty/CMakeLists.txt，找到**libsndfile相关的列，进行修改
把这行的路径调整成我这样就解决了 ，这个so的库文件按自己搜索到的填

set(LIBSNDFILE /usr/lib/aarch64-linux-gnu/libsndfile.so.1.0.31   PARENT_SCOPE)
