dnl find_apr.m4 : locate the APR include files and libraries
dnl
dnl This macro file can be used by applications to find and use the APR
dnl library. It provides a standardized mechanism for using APR. It supports
dnl embedding APR into the application source, or locating an installed
dnl copy of APR.

dnl   where srcdir is the location of the bundled APR source directory, or
dnl   empty if source is not bundled.
dnl
dnl   where blddir is the location where the bundled APR will will be built,
dnl   or empty if the build will occur in the srcdir.

dnl   apr_found : "yes", "no", "reconfig"
dnl
dnl   apr_config : If the apr-config tool exists, this refers to it. If
dnl                apr_found is "reconfig", then the bundled directory
dnl                should be reconfigured *before* using apr_config.
dnl
dnl Note: this macro file assumes that apr-config has been installed; it
dnl       is normally considered a required part of an APR installation.
dnl
dnl If a bundled source directory is available and needs to be (re)configured,
dnl then apr_found is set to "reconfig". The caller should reconfigure the
dnl (passed-in) source directory, placing the result in the build directory,
dnl as appropriate.
dnl
dnl If apr_found is "yes" or "reconfig", then the caller should use the
dnl value of apr_config to fetch any necessary build/link information.
