# This file sets up Gurobi for CMake. Once done this will define
#
#   GUROBI_FOUND           - system has GUROBI
#   GUROBI_INCLUDE_DIRS    - the GUROBI include directories
#   GUROBI_LIBRARIES       - Link these to use GUROBI
#
#  In your CMakeLists file, you need to add, e.g. (modify it if necessary):
#        if (GUROBI_FOUND)
#            message(STATUS "Gurobi include dir: " ${GUROBI_INCLUDE_DIRS})
#            message(STATUS "Gurobi libraries: " ${GUROBI_LIBRARIES})
#            target_compile_definitions(${PROJECT_NAME} PUBLIC HAS_GUROBI)
#            target_include_directories(${PROJECT_NAME} PRIVATE ${GUROBI_INCLUDE_DIRS})
#            target_link_libraries(${PROJECT_NAME} PRIVATE ${GUROBI_LIBRARIES})
#        endif()
