I am trying to recompile Apache, and I am stumped by this directive:

--with-ssl=DIR SSL/TLS toolkit (OpenSSL)

What EXACTLY am I supposed to put here? It's so vague. Am I supposed to
put the folder to my openssl binary? In that case the binary is located at
"/usr/bin/openssl".

Or am I supposed to put "/usr/include/openssl/", which contains all the *.h
files?

Or, am I supposed to put "/usr/share/ssl/", which contains files like CA
cert.pem certs lib misc openssl.cnf private stunnel.cnf?

The documentation is SOOOO terrible.
