[Cmpl] Error connecting to CPLEX

[Mike Steglich]

The entry ScipFileName = ../Thirdparty/scip/scip-3.1.0.win.x86.msvc.opt.spx.ld.exe is fine.  

As mentioned before, please move the required libs (scip-3.1.0.win.x86.msvc.opt.spx.ld.dll and scip-3.1.0.win.x86.msvc.opt.spx.ld.lib)  into Cmpl/Frameworks …
