按照paddle文档教程编写自定义算子时，报下面的错误，链接库无法找到。

RuntimeError: (PreconditionNotMet) The third-party dynamic library (/public/home/miaozhao/kazheng_fourpoint/card_crop_paddle_orgpaddle_fuzhi/ppdet/relu/build/custom_setup_ops/lib.linux-x86_64-3.8/custom_setup_ops.so) that Paddle depends on is not configured correctly. (error code is /public/home/miaozhao/kazheng_fourpoint/card_crop_paddle_orgpaddle_fuzhi/ppdet/relu/build/custom_setup_ops/lib.linux-x86_64-3.8/custom_setup_ops.so: undefined symbol: _ZN6paddle17OpMetaInfoBuilderC1EOSsm)
Suggestions:
1. Check if the third-party dynamic library (e.g. CUDA, CUDNN) is installed correctly and its version is matched with paddlepaddle you installed.
2. Configure third-party dynamic library environment variables as follows:
- Linux: set LD_LIBRARY_PATH by `export LD_LIBRARY_PATH=...`
- Windows: set PATH by `set PATH=XXX; (at /paddle/paddle/fluid/platform/dynload/dynamic_loader.cc:285)
