  --with-apr=SRCDIR        define a space-separated list of directories to

                           search for the APR source code. If, instead of a

                           directory, an apr-config executable name is passed,

                           APR-Config Mode is enabled (see below). Defaults to

                           "srclib/apr ../apr"

  --with-apr-util=SRCDIR   define a space-separated list of directories to

                           search for the APR-util source code. Defaults to the

                           same location as the --with-apr SRCDIR, but with

                           "apr" replaced with "apr-util" or "aprutil". Ignored

                           in APR-Config Mode.

APR-Config Mode:

  When passing an apr-config executable to --with-apr, buildconf will attempt to

  copy build scripts from various installed locations on your system instead of

  an APR source tree. This allows you to configure httpd from source without

  also requiring you to download the APR and/or APR-util sources.

  For example:

      ./buildconf --with-apr=apr-1-config

  For this functionality to work reliably, you must have automake >= 1.12 and be

  using a distribution that includes both find_apr.m4 and find_apu.m4 in the

  --installbuilddir pointed to by apr-config.

Environment variables used by buildconf:

  AUTOCONF           autoconf executable name [autoconf]

  AUTOMAKE           automake executable name [automake]

  AUTOHEADER         autoheader executable name [autoheader]
