+If you installed the OpenSSL libraries from source, it may be necessary
+to let configure know where they are, by passing configure one of the
+--with-openssl-* parameters.
+
+@example
+--with-openssl=DIR OpenSSL library and headers prefix
+--with-openssl-include=DIR OpenSSL headers directory
+ (Default is OPENSSL_DIR/include)
+--with-openssl-lib=DIR OpenSSL library directory
+ (Default is OPENSSL_DIR/lib)
+@end example
