Missing libmariadbcpp.so in clp-package Docker execution image

[coderabbitai]

Description

The shared library libmariadbcpp.so, which both spider_scheduler and spider_worker dynamically link to, is not included in the package execution environment (the clp-package Docker execution image). This will cause runtime failures when attempting to execute these binaries.

Impact

The spider scheduler and worker binaries cannot run in the Docker execution environment without this library present.

We found the size of the currently produced build/deps/cpp/mariadb-connector-cpp-build/libmariadbcpp.so is as large as 22MB, because by default the binaries are build with CMAKE_BUILD_TYPE "RelWithDebInfo"

https://github.com/mariadb-corporation/mariadb-connector-cpp/blob/912330a3480167c988803205e6897870e639a91f/CMakeLists.txt#L501

A similar size is also found with the latest binaries in the official release tar: https://dlm.mariadb.com/4464862/Connectors/cpp/connector-cpp-1.1.7/mariadb-connector-cpp-1.1.7-ubuntu-jammy-amd64.tar.gz

We should aim to reduce the image size as we integrate the MariaDb shared libraries. Therefore, we should try building with CMAKE_BUILD_TYPE "Release", which cuts down the libmariadbcpp.so size to 2.22 MB
