[Cmpl] Error connecting to CPLEX

[Indrajit Sen Gupta]

These are the three files that I have in /Thirdparty/SCIP/

scip-3.1.0.win.x86.msvc.opt.spx.ld.dll
scip-3.1.0.win.x86.msvc.opt.spx.ld.exe
scip-3.1.0.win.x86.msvc.opt.spx.ld.lib

And this is the line in /bin/cmpl.opt

ScipFileName = ../Thirdparty/SCIP/scip-3.1.0.win.x86.msvc.opt.spx.ld.exe

Regards,
Indrajit
