#   The makefile takes in input the -I directives for all the external       #
#   libraries needed by MILPSolver, i.e., core SMS++ and those of all the    #
#   individual *MILPSolver (currently Cplex, Gurobi, SCIP, HiGHS). These are #
#   *not* copied into $(MILPSINC): adding those -I directives to the compile #
#   commands will have to done by whatever "main" makefile is using this.    #
#   Analogously, any external library and the corresponding -L< libdirs >    #
#   will have to be added to the final linking command by  whatever "main"   #
#   makefile is using this.                                                  #

#   Note that, conversely, $(SMS++INC) is also assumed to include any        #
#   -I directive corresponding to external libraries needed by SMS++, at     #
#   least to the extent in which they are needed by the parts of SMS++       #
#   used by MILPSolver.                                                      #
