[Bonmin] Setting up Bonmin 1.8.7 with CPLEX 12.9

Thu Jun 6 05:12:09 EDT 2019

Hi Christoph,
Sorry those pages are quite old and they should be updated.
I tried and I think that Windows Linux Subsystem is a good option (it looks
to me like it was made for those type of things).
Best regards,
Pierre
