[Symphony] 'Unresolved external symbol' linking error with 'milp.c' example

[Yiqing Zhong]

Hi!
I'm not sure what paths or dependencies of include and lib you set,  
but I tried the same example in 'SYMPHONY-5.1.0-win32-msvc-v8', with  
Visual C++ express 2005, that's ok! The default definations are kept,  
I don't change anything.

But in SYMPHONY-5.1.10, I tried to change the solver to CPLEX, the  
same link errors ("LNK2019") were happened, even I set the paths of  
include and lib. I didn't fix that yet. If you fix yours, could you  
show that :) Thank you!

Bests!

Terry
