Thanks, Barry. Still not work after including ${DLIB}

For the sequential version without PETSc, it can be compiled without problem using the following makefile. The parallel version without CGAL can also be compiled successfully. However, when I tried to use PETSc together with CGAL library, I cannot compile the code. My questions is: How can I modify the makefile? Do I need to reconfigure PETSc with special flags? All the makefile samples are shown below.
