[Scip] Linking error in Windows

[Ambros Gleixner]

Hi Shahin,

are you using the VS libs from the SCIP website or did you build SCIP on 
your own?

SCIPinfinity() is different in debug and optimized mode.  When you 
compile with the NDEBUG flag, SCIPinfinity() becomes a macro and is not 
available as a function.

Your problem might be, that your SCIP lib is built in optimized mode 
(with NDEBUG), but your VRP code in debug mode.  Can you try adding 
NDEBUG to your compiler flags?
