[Scip] linking error with the new VS10 libs

[Shahin Gelareh]

Dear Scippers

I have  a code which compiles and links fine in linux.
When I try to compile it in VS10 using the recently released windows
libraries (3.0.2) I get the following errors.

Even in the VRP example, it uses "SCIPcreateVar" and it compiles fine in
VS10 but when I use SCIPcreateObjVar instead,  I get the linking error.
It seems like an error regarding C++ wrapper classes.

I wonder if I am missing anything here? anything extra to be linked
together? any preprocessor to declare?

thank you in advance.
