[stunnel-users] Configure Error

Hi

I am running into an issue when I go into the src directory and I run the configure command, I get

configure: error: Could not find your TLS library installation dir Use --with-ssl option to fix this problem

I am trying to upgrade our version of stunnel. Our SME left and now I am trying to upgrade stunnel to fix a vulnerability . I am being told to use TLS1.1 or higher

Here is our current version of stunnel

$ ./stunnel -version

stunnel 4.15 on x86_64-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP

Any help would be appreciated.
