You should ask the compiler to link the libraries at the time a contract is compiled by either FatalError: Fatal error not processed correctly - this should be reported as an issue.

Are optimizations always enabled or always disabled? // Choose which types of invariants should be reported to the user: contract, reentrancy. Asking for help, clarification, or responding to other answers. // Required: Source code language. // If the option is omitted, "ipfs" is used by default. // If remappings are used, this source file should match the global path. // except underflow/overflow for Solidity >=0.8.7. The same interface is provided by all distributions of the compiler. When publishing a contract that imports other contracts, the main contract and all of its imported contracts will be published - each to their own address.
