autoconf: Optional Features

1 16.5 Optional Features
1 ======================
1 
1 If the package supports it, you can cause programs to be installed with
1 an extra prefix or suffix on their names by giving `configure' the
1 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
1 
1    Some packages pay attention to `--enable-FEATURE' options to
1 `configure', where FEATURE indicates an optional part of the package.
1 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
1 is something like `gnu-as' or `x' (for the X Window System).  The
1 `README' should mention any `--enable-' and `--with-' options that the
1 package recognizes.
1 
1    For packages that use the X Window System, `configure' can usually
1 find the X include and library files automatically, but if it doesn't,
1 you can use the `configure' options `--x-includes=DIR' and
1 `--x-libraries=DIR' to specify their locations.
1 
1    Some packages offer the ability to configure how verbose the
1 execution of `make' will be.  For these packages, running `./configure
1 --enable-silent-rules' sets the default to minimal output, which can be
1 overridden with `make V=1'; while running `./configure
1 --disable-silent-rules' sets the default to verbose, which can be
1 overridden with `make V=0'.
