[SCIP] CPLEX 12.7 and SCIP compile error

[Marc Pfetsch]

Just as an additional comment: I have now tried CPLEX 12.7 with SCIP,
and there are several cases where I run into problems (after fixing the
compile problems as indicated by Stefan). So just as a warning, it might
happen that the SCIP interface throws asserts (in debug mode) or you
might get wrong solutions.

I have tried to debug this, but the problem is not easy to find. For the
meantime, I would say that it makes sense to use older versions of
CPLEX, if possible.
