Next, edit Makefile.PL and change LIBS and INC to include the appropriate
    path information to the required libMagick library. You will also need
    library search paths (-L) to JPEG, PNG, TIFF, etc. libraries if they were
    included with your installed version of ImageMagick. If an extension
    library is built as a shared library but not installed in the system's
    default library search path, you may need to add run-path information
    (often -R or -rpath) corresponding to the equivalent library search
    path option so that the library can be located at run-time.
