Look into dlopen/dlsym. These functions let you load libraries at
runtime by hand. Design an interface for your program to interact with
the library, for instance initialization functions/communication
functions. It's not too difficult.

Alternatively, you could have a plugin process running externally and
communicate with some kind of IPC, such as shared memory, named pipes,
or sockets.
