Undefined reference to `mysqlx::abi2::r0::Schema::Schema(mysqlx ::abi2::r0::Session&)'

Question

I had a problem when linking to mysqlcppconn (version 8.0.30) (similar to the issue described here).

Here is my code:

        mysqlx::Session sess2("localhost", 33060,
                                   "root", "test",
                                   "postManufDB");
        Schema mySchema(sess2);

CMakeLists.txt (used to compile my app):

cmake_minimum_required(VERSION 3.5)
project(PostManuf VERSION 0.1 LANGUAGES CXX)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CPP_CON_VERSION_MAJOR 8)
set(CPP_CON_LIB mysqlcppconn${CPP_CON_VERSION_MAJOR})
set(FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR "/usr/local/mysql/connector-c++-8.0.30")
set(CPP_CON_LIB_INC ${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/include/)
set(CPP_CON_LIB_LINK ${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/lib64/debug/)
include_directories(${CPP_CON_LIB_INC})
link_directories(${CPP_CON_LIB_LINK})

set(PROJECT_SOURCES
        main.cpp
        mainwindow.cpp
        mainwindow.h
)

add_executable(PostManuf ${PROJECT_SOURCES})

target_link_libraries(PostManuf PRIVATE ${CPP_CON_LIB})

Error:

mainwindow.cpp:(.text+0x3ab6): undefined reference to `mysqlx::abi2::r0::Schema::Schema(mysqlx
::abi2::r0::Session&)'

Steps I've followed:

Download mysqlcppconn binaries and used it for development
Compiled mysqlcppconn binary from source and linked to it
Added add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0) to CMakeLists.txt, but then I have a lot more errors:

I can run the application successfully when using more common classes (e.g. Session). But when using Schema, I can't link.
