[Bonmin] Setting up Bonmin 1.8.7 with CPLEX 12.9

Thu Jun 6 06:52:47 EDT 2019

Hi,

for this particular one about the build system type, you could try 
running configure with --build=x86_64-pc-mingw32

The autotools version used by Bonmin is still a bit old and doesn't know 
how to handle msys yet.

These days, Msys2 and/or Windows Subsystem for Linux are much better options. We have not really kept up the CYGWIN support, since these better options exist and since it has some "eccentricities."
