16.5 Optional Features
======================

If the package supports it, you can cause programs to be installed with
an extra prefix or suffix on their names by giving ‘configure’ the
option ‘--program-prefix=PREFIX’ or ‘--program-suffix=SUFFIX’.

   Some packages pay attention to ‘--enable-FEATURE’ and
‘--disable-FEATURE’ options to ‘configure’, where FEATURE indicates an
optional part of the package.  They may also pay attention to
‘--with-PACKAGE’ and ‘--without-PACKAGE’ options, where PACKAGE is
something like ‘gnu-ld’.  ‘./configure --help’ should mention the
‘--enable-...’ and ‘--with-...’ options that the package recognizes.

   Some packages offer the ability to configure how verbose the
execution of ‘make’ will be.  For these packages, running ‘./configure
--enable-silent-rules’ sets the default to minimal output, which can be
overridden with ‘make V=1’; while running ‘./configure
--disable-silent-rules’ sets the default to verbose, which can be
overridden with ‘make V=0’.
