How to keep the behavior the same in v4 after upgrading from v3?

After upgrading from v3, the plugin no longer works.

Here is the config:

const cesiumSource = "./node_modules/cesium/Build/Cesium"
const cesiumBaseUrl = './assets'
export default defineConfig {
   define: {
		CESIUM_BASE_URL: JSON.stringify(cesiumBaseUrl),
   },
   plugin: [
     viteStaticCopy({
			targets: [
				{ src: `${cesiumSource}/ThirdParty`, dest: cesiumBaseUrl },
				{ src: `${cesiumSource}/Workers`, dest: cesiumBaseUrl },
				{ src: `${cesiumSource}/Assets`, dest: cesiumBaseUrl },
				{ src: `${cesiumSource}/Widgets`, dest: cesiumBaseUrl },
			],
		}),
   ]
}

In v4, the way the collectCopyTargets function computes the dest path has changed. As a result, the built files are now copied to the ./assets//node_modules/cesium/Build/Cesium/ directory. In v3, the files were placed directly into the ./assets/ directory.
This change in v4 also prevents Cesium from accessing these static files correctly under the dev server: because the fileMap keys no longer match, those static files requested by Cesium are all incorrectly returned with index.html.

Is there any solution to solve these?

I guess rename.stripBase is what you want.
