虽然ui库的css被分割到不同的文件中了，但是在使用ui库时，依然会把所有css文件编译到产物中？

只引入了button，理论上来说最终只会编译button的样式到产物中

import { Button } from 'component-lib';

但是假设component-lib里面还有其他组件，那么其他的组件的样式也会被编译到产物中

The solution is same too, please add component entries into lib.entries

加了多入口，也每个入口生成了一个css文件。但是当实际使用用这个ui库的时候，依然会把每一个css文件都引入。相当于实际使用的时候css没有被tree-shaking
