[SCIP] Gurobi + SCIP

[Matthias Walter]

Hi Vincent,

please look into scip/cmake/Modules/FindGUROBI.cmake. In the 
find_library call, cmake searches for different gurobi libraries. 
Apparently, gurobi90 is not searched for (I do have a libgurobi.so.9.0.0 
on my machine, but probably the file extension probably does not count 
for cmake). So you can easily add a "gurobi90" to the NAMES parameter of 
find_library and then retry.

Best,
Matthias
