重现步骤

1. source /usr/local/Ascend/ascend-toolkit/latest/set_env.sh
2. cd ops-blas && bash build.sh --pkg --soc=ascend950
3. ./build_out/cann-*.run --install --install-path=/usr/local/Ascend
4. 将 blas/copy/README.md 中 aclblasScopy 的调用示例保存为 example.cpp
5. 使用 docs/zh/develop/compile_and_run_example.md 中的 CMakeLists.txt 编译并运行

预期结果

README 调用示例能正确编译并运行出结果。
