Maybe need dlopen/dlclose to deal with link errors.

ex.)
int main(int ac, char *av[])

	void *dl_handle_libnvmmlite_video = dlopen("libnvmmlite_video.so", RTLD_LAZY | RTLD_GLOBAL);

	...

	// [ad hoc] dynamic load for nvv4l2decoder.
	dlclose(dl_handle_libnvmmlite_utils);
	dlclose(dl_handle_libnvmmlite_video);

	return EXIT_SUCCESS;
