描述
## Expected Behavior
static lib should be linked only one time.
## Current Behavior
Some static libs are linked multiple times.
in [`src/sdk/CMakeLists.txt`](https://github.com/4paradigm/OpenMLDB/blob/2f85d12cd8dadd3a1ec822e1f591632341f3b23f/src/sdk/CMakeLists.txt#L52)
`set(SDK_LIBS openmldb_sdk openmldb_catalog client zk_client schema openmldb_flags openmldb_codec openmldb_proto base hybridse_sdk zookeeper_mt ${VM_LIBS} ${LLVM_LIBS} ${BRPC_LIBS} ${ZETASQL_LIBS}) `
where `${VM_LIBS} ${LLVM_LIBS} ${BRPC_LIBS} ${ZETASQL_LIBS} ` are not necessary and already linked by `hybridse_sdk`.
It may cause unexpected fault if we link multiple times. see [here](https://github.com/4paradigm/OpenMLDB/runs/5425348767?check_suite_focus=true)
## Possible Solution
It is not obvious what will happen if we link a static lib multiple times. We have to figure it out what are the correct way to do this.
I believe there are other places where there are duplicate links except the `SDK_LIBS`. But it for now does not trigger any error or unexpected crash.

调研方向
The issue points to src/sdk/CMakeLists.txt line 52 where SDK_LIBS includes duplicate static libraries. First, examine the CMakeLists.txt to understand the library dependencies, particularly how hybridse_sdk includes VM_LIBS, LLVM_LIBS, BRPC_LIBS, and ZETASQL_LIBS. Then, search for other duplicate links in the codebase. Test the build after removing the duplicates to ensure no linking errors occur.
