compile issue with Gurobi 8.1 on Linux

[fizwit]

Linux 14.04, GCCcore 5.4.0, Gurobi 8.1
Made changes to FindGUROBI.cmake for Linux to allow Cmake to fine Include and library paths for Gurobi. Now getting "undefined reference" errors. Has the API for Gurobi changed since version 5? Have you tested with version 8?

Gurobi 8.0 works. These are linker errors -- are you sure you updated the library path correctly?
