Dynamic VS Static linking

[saif kandil]

Hello folks,

I created this simple solution to try to link absl, protobuf, and grpc together to see if they work without problems, and I have figured out that static linking is working perfect however the dynamic linking is not:

Static linking status: https://github.com/k0T0z/absl-proto-grpc-ci/actions/runs/10282329751/job/28453797159

Dynamic linking status: https://github.com/k0T0z/absl-proto-grpc-ci/actions/runs/10283676833/job/28458035515

The error exists in the job file but here is a version of it:

```

[ 53%] Linking CXX shared library libprotobuf.so

make[1]: *** [CMakeFiles/Makefile2:142: CMakeFiles/libprotobuf.dir/all] Error 2

make: *** [Makefile:136: all] Error 2

```

Can anyone please explain it to me? Why this happened? I built absl from scratch.

Don't bother guys, I just saw new options that can be passed to Abseil: https://github.com/abseil/abseil-cpp/blob/3848ed7f1b13259a8ddd35dc56bf216ecd36d968/ci/linux_gcc-latest_libstdcxx_cmake.sh#L33
