<h2>
SYNOPSIS
</h2>
<p class="indent" style="white-space:nowrap;">
<code>CHECK_SSL</code>
</p>
<h2>
DESCRIPTION
</h2>
<div class="indent">
<p>
This macro will check various standard spots for OpenSSL including a
user-supplied directory. The user uses '--with-ssl' or
'--with-ssl=/path/to/ssl' as arguments to configure.
</p>
<p>
If OpenSSL is found the include directory gets added to CFLAGS and CXXFLAGS
as well as '-DHAVE_SSL', '-lssl' & '-lcrypto' get added to LIBS, and
the libraries location gets added to LDFLAGS. Finally 'HAVE_SSL' gets set
to 'yes' for use in your Makefile.in I use it like so (valid for gmake):
</p>
<pre>
HAVE_SSL = @HAVE_SSL@
ifeq ($(HAVE_SSL),yes)
SRCS+= @srcdir@/my_file_that_needs_ssl.c
endif
</pre>
<p>
For bsd 'bmake' use:
</p>
<pre>
.if ${HAVE_SSL} == "yes"
SRCS+= @srcdir@/my_file_that_needs_ssl.c
.endif
</pre>
</div>
