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
dnl APR_FIND_APR(srcdir, builddir, implicit-install-check, acceptable-majors)
dnl
dnl   where srcdir is the location of the bundled APR source directory, or
dnl   empty if source is not bundled.
dnl
dnl   where builddir is the location where the bundled APR will will be built,
dnl   or empty if the build will occur in the srcdir.
dnl
dnl   where implicit-install-check set to 1 indicates if there is no
dnl   --with-apr option specified, we will look for installed copies.
dnl
dnl   where acceptable-majors is a space separated list of acceptable major
dnl   version numbers. Often only a single major version will be acceptable.
dnl   If multiple versions are specified, and --with-apr=PREFIX or the
dnl   implicit installed search are used, then the first (leftmost) version
dnl   in the list that is found will be used.  Currently defaults to [0 1].
dnl
dnl Sets the following variables on exit:
dnl
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* Nikos Mavrogiannopoulos
