[SCIP] Problem compiling ParaSCIP from scipoptsuite-7.0.0

[Sergey Smirnov]

Hello,

I’ve downloaded scipoptsuite-7.0.0, built scip successfully, but when I tried to build UG with MPI, it failed with the following compilation error:
vagrant at ubuntu-bionic:~/scipoptsuite-7.0.0$ make ug COMM=mpi

...

It seems that tempScip2  really is not defined. There is similar code (without such error) in some of the case clauses earlier in the function. How to fix it correctly?
