Linker error with gcc 10 and multiple translation units including superior_mysqlpp.hpp

[daniele77]

With recent compilers (e.g., gcc 10) the linking of multiple translation units including the header superior_mysqlpp.hpp results in an error. The linker complains about multiple definitions of SuperiorMySqlpp::mapSecondGetter.

This is because of this definition:

SuperiorMySqlpp/include/superior_mysqlpp/master_slave_connection_pools.hpp

Line 20 in 05421a8

auto mapSecondGetter = [](auto&& item) -> auto& { return std::forward<decltype(item)>(item).second; };

)

I provided a solution to this issue in the PR #131
