只有在代码使用时才能拥有动态库吗？

I have a large program that may be linked against some external libraries, but these are only needed for some specific functions. However, even if I don't use these functions, the external libraries are still required. Can I do something (preferably at compile or link time) so that the libraries are only required if the functionality they provide is requested?I have a large program that may be linked again
