Error Importing/compiling: WormholeRelayerSDK.sol

[teterabOb]

I'm participating in SIGMA Sprint, and to perform cross-chain transfers of ERC-20 tokens, I'm following the tutorial from the documentation.

Framework:

• hardhat + foundry

Command run:

• npx hardhat compile
• forge build

To install the Wormhole Solidity SDK, I'm using Git submodules.

[submodule "lib/wormhole-solidity-sdk"]
	path = lib/wormhole-solidity-sdk
	url = https://github.com/wormhole-foundation/wormhole-solidity-sdk

Cuándo creo el contrato sender me esta dando error al compilar.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.13;

import "lib/wormhole-solidity-sdk/src/WormholeRelayerSDK.sol";
import "lib/wormhole-solidity-sdk/src/interfaces/IERC20.sol";

contract CrossChainSender is TokenSender {
} 

The error I got is as follows:

Compiler run failed:
Error (2904): Declaration "Base" not found in "lib/wormhole-solidity-sdk/src/WormholeRelayerSDK.sol" (referenced as "./WormholeRelayerSDK.sol").
 --> lib/wormhole-solidity-sdk/src/TokenBase.sol:8:1:
  |
8 | import {Base} from "./WormholeRelayerSDK.sol";

Basically, in the file ./WormholeRelayerSDK.sol, the line import {Base} from "./Base.sol"; is causing an error. However, I checked, and I can't figure out what's wrong. The contract exists, and the import seems correct.

// SPDX-License-Identifier: Apache 2
pragma solidity ^0.8.13;

import "./interfaces/IWormholeReceiver.sol";
import "./interfaces/IWormholeRelayer.sol";
import "./Chains.sol";
import "./Utils.sol";
import {Base} from "./Base.sol";
import {TokenBase, TokenReceiver, TokenSender} from "./TokenBase.sol";
import {CCTPBase, CCTPReceiver, CCTPSender} from "./CCTPBase.sol";
import {CCTPAndTokenBase, CCTPAndTokenReceiver, CCTPAndTokenSender} from "./CCTPAndTokenBase.sol";

In order to solve this issue I'm just importing TokenBase.sol instead of WormholeRelayerSDK.sol but it should be giving an error by just importing the WormholeRelayerSDK.sol
