It seems like the linker cannot find the MySQL Connector/C++ library file named mysqlcppcon. This could be due to several reasons:

1. The library name might be incorrect in the target_link_libraries command.
2. The path specified in link_directories may not contain the actual library files or is incorrect.
3. If you are using a different version of the connector or if your system is 32-bit, the library might be under a different folder instead of lib64.

Here’s what you can do to resolve the issue:

• Verify that the library name is correct. Often, the library file is named mysqlcppconn. If this is the case, update your target_link_libraries command to use the correct name.

• Check if the library files (.lib for static linking or .dll and .dll.a for dynamic linking on Windows) are actually present in ${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/lib64.

• If your system is 32-bit or uses a different directory structure, ensure that you’re looking in the right directory for your libraries.

• You might need to specify the exact name of the library file without the extension in your target_link_libraries, e.g., if there’s a file named libmysqlcppconn.lib, just mention mysqlcppconn.

Here’s an example of how you might adjust your CMake configuration:

set(FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR "C:/MySQL/MySQL Connector C++ 8.4")
include_directories(${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/include)

link_directories(${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/lib64)

target_link_libraries(2024__TAB_DSA__8_BRODZIAK
 PRIVATE cpr::cpr
 mysqlcppconn # Assuming 'mysqlcppconn' is the correct name of your library
)

target_compile_features(2024__TAB_DSA__8_BRODZIAK PRIVATE cxx_range_for)

If none of these steps solve your problem, consider double-checking that you have installed MySQL Connector/C++ correctly and that all necessary environment variables are set up properly. Additionally, make sure that you’re using compatible versions of MySQL Connector/C++ with your compiler and build tools.
