I know Alexandre Duret-Lutz  has answered your question. but wouldn't it be 
cleaner to add to your configure.ac the following:

AC_DEFINE(SSH, $SSH, [Location of SSH executable])

Then, within you code you would have something like

/* some_file.hpp */

#ifndef SOME_FILE_HPP
#define SOME_FILE_HPP

#include <string>

const std::string&
getSshPath();


#endif // !def SOME_FILE_HPP

/* some_file.cpp */

#ifdef HAVE_CONFIG_H
#include "config.h"
#endif //HAVE_CONFIG_H

#include "some_file.hpp"

const std::string&
getSshPath()
{
	static const std::string sshPath = SSH;
	return sshPath;
}

Just my $0.02
