What does that mean? cbc-generic is an executable and it does not seem
possible to tell it to use Cplex instead of Clp.

Also, the library does not seem to work with Cplex. The following simple
code crashes with a segmentation fault at the end of the root node:

   OsiCpxSolverInterface solver;
   solver.readMps("dcmulti");
   CbcModel model(solver);
   model.branchAndBound();

The above code works if Cpx is replaced by Clp.
