On Unix systems it is not possible to dynamically load a library 
shared by a static executable, I don't know if it works 
differently for Windows.

This is because it is absolutely necessary to link libdl 
dynamically, you cannot link static.

For GNU/Linux systems there is this alternative to dlopen/dlsym 
that does not require dynamic link:
