排查过程：

1、检查代码，在官方samples 的代码也会报错。排除代码问题
2、检查cmakelists.txt ,和 build.sh 。可能是这个的问题
在官方samples 里面按照流程先执行 env.sh 后，再回到当前自己的工程，运行./build.sh --mlu-arch=SD5223C --cpu-arch=aarch64，发现没有错误。排除后，发现如果：export NEUWARE_HOME="/usr/local/neuware" 换成export NEUWARE_HOME=/mnt/data/ef2301-sdk-0.10.0/board/develop_workspace/inference/mm/neuware （就是复制到其他地方），就可正常。

可能是 cmakelists里面的如下代码导致的错误：
