    Yeah, the docs are quite explicit about the need to link with the
    libs. Your Makefile could be as simple as:

    CXXFLAGS= -I/usr/local/include
    LDFLAGS=  -L/usr/local/lib -lboost_filesystem -lboost_program_options                 
    
    fubar: fubar.cpp
        $(CXX) $(CXXFLAGS) $(LDFLAGS) -o fubar fubar.cpp
