Wrong findGUROBI

[akshitj1]

https://github.com/mit-acl/faster/blob/3af4e9b276452694b6d527f13eaac926bef0138b/faster/FindGUROBI.cmake#L24 In the findGUROBI, both GUROBI_LIBRARY and GUROBI_CXX_LIBRARY matches to same libgurobi_c++.a as same pattern is present in both. This results to not linking of .so files eg. libgurobi91.so. This leads to undefined reference errors in gurobi.

Hi @akshitj1

Could you try to compile it again with the last commit (fc19020)? Let me know if that still doesn't solve the problem

Also, remember to do this

For now I have quick fixed with this:

find_library( GUROBI_LIBRARY 
              NAMES libgurobi91.so
              PATHS "$ENV{GUROBI_HOME}/lib" 
                    "/Library/gurobi502/mac64/lib"
                    "C:\\libs\\gurobi502\\lib"
              )

find_library( GUROBI_CXX_LIBRARY 
              NAMES gurobi_c++
              PATHS "$ENV{GUROBI_HOME}/lib" 
                    "/Library/gurobi502/mac64/lib"
                    "C:\\libs\\gurobi502\\lib"
              )

I will send PR with more robust fix later.

Perfect, thanks. I've just updated the FindGurobi.cmake with the one available in the official page of gurobi (link), and I've modified it to make it independent of the version of Gurobi.

Feel free to create a PR with any better/more robust solutions.
