What’s the process to switch to the new Gurobi release (8.0) ?

I have not tried it yet but I believe the process should be:

1. Install gurobi 8.0
2. Set your `GUROBI_HOME` variable to the new installation
3. `julia> Pkg.build("Gurobi")`

GUROBI\_HOME was already changed and and Pkg.build(“Gurobi”) didn’t do it. I had to remove the package and reinstall it.
