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