   5 dnl find_apr.m4 : locate the APR include files and libraries
   6 dnl
   7 dnl This macro file can be used by applications to find and use the APR
   8 dnl library. It provides a standardized mechanism for using APR. It supports
   9 dnl embedding APR into the application source, or locating an installed
  10 dnl copy of APR.
  11 dnl
  12 dnl APR_FIND_APR([srcdir [, builddir, implicit-install-check]])
  13 dnl
  14 dnl   where srcdir is the location of the bundled APR source directory, or
  15 dnl   empty if source is not bundled.
  16 dnl
  17 dnl   where blddir is the location where the bundled APR will will be built,
  18 dnl   or empty if the build will occur in the srcdir.
  19 dnl
  20 dnl   where implicit-install-check set to 1 indicates if there is no
  21 dnl   --with-apr option specified, we will look for installed copies.
  22 dnl
  23 dnl Sets the following variables on exit:
  24 dnl
  25 dnl   apr_found : "yes", "no", "reconfig"
  26 dnl
  27 dnl   apr_config : If the apr-config tool exists, this refers to it. If
  28 dnl                apr_found is "reconfig", then the bundled directory
  29 dnl                should be reconfigured *before* using apr_config.
  30 dnl
  31 dnl Note: this macro file assumes that apr-config has been installed; it
  32 dnl       is normally considered a required part of an APR installation.
  33 dnl
  34 dnl If a bundled source directory is available and needs to be (re)configured,
  35 dnl then apr_found is set to "reconfig". The caller should reconfigure the
  36 dnl (passed-in) source directory, placing the result in the build directory,
  37 dnl as appropriate.
  38 dnl
  39 dnl If apr_found is "yes" or "reconfig", then the caller should use the
  40 dnl value of apr_config to fetch any necessary build/link information.
