How to install or Where is libclangTooling

EDIT:
Issue solved. By linking with libclang-cpp.so.

Hi all,
I have clang-13.0.0-2, and llvm-13.0.0-3 installed.
I am trying to build an out of tree clang pass with CMake.

In CMakeLists.txt, I specified it would be linked with libclangTooling.

target_link_libraries(
      ${tool}
      clangTooling
    )

But I got an error:

/usr/bin/ld: cannot find -lclangTooling

Then I checked the clang lib directory /lib/clang/13.0.0/lib/linux. There is no libclangTooling.so, but the libclang_rt.*.so.

Please tell me how to install the libclangTooling, or where I can find it. Thanks!
