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])
dnl
dnl where srcdir is the location of the bundled APR source directory, or
dnl empty if source is not bundled.
dnl
dnl
dnl Sets the following variables on exit:
dnl
dnl apr_libdir : A custom directory to use for linking (the -L switch).
dnl If APR exists in a standard location, this variable
dnl will be empty
dnl
dnl apr_la_file : If a libtool .la file exists, this will refer to it. If
dnl there is no .la file, then this variable will be empty.
dnl
dnl apr_includes : Where the APR includes are located, if a non-standard
dnl location. This variable has the format "-Idir -Idir".
dnl It may specify more than one directory.
dnl
dnl apr_srcdir : If an APR source tree is available and needs to be
dnl (re)configured, this refers to it.
dnl
dnl apr_config : If the APR config file (APRVARS) exists, this refers to it.
dnl
dnl apr_found : "yes", "no", "reconfig"
dnl
dnl Note: At this time, we cannot find *both* a source dir and a build dir.
dnl If both are available, the build directory should be passed to
dnl the --with-apr switch (apr_srcdir will be empty).
dnl
dnl Note: the installation layout is presumed to follow the standard
dnl PREFIX/lib and PREFIX/include pattern. If the APR config file
dnl is available (and can be found), then non-standard layouts are
dnl possible, since it will be described in the config file.
dnl
dnl If apr_found is "yes" or "reconfig", then the caller should link using
dnl apr_la_file, if available; otherwise, -lapr should be used (and if
dnl apr_libdir is not null, then -L$apr_libdir). If apr_includes is not null,
dnl then it should be used during compilation.
dnl
dnl If a source directory is available and needs to be (re)configured, then
dnl apr_srcdir specifies the directory and apr_found is "reconfig".
