Command explanations: This switch is used to
avoid the configuration routine asking for confirmation of the
installation directories (which we pass to configure).--with-DIR_MAN=/usr/share/man: This is used
because despite the fact we pass --prefix=/usr, the
configure routine tries to install the man pages in /usr/local/man instead of the correct
place.--with-ZIP=yes --with-DIR_GZLIB=/usr/lib: This
enables support for the handling of TIFF images with
deflate-encoded data.--with-JPEG=yes --with-DIR_JPEGLIB=/usr/lib: Use
these switches to enable support for the handling of TIFF
images with JPEG-encoded data.
