Jeff,

Thanks so much for the help.

It turns out that in our environment we don't need most of the link
config stuff as we have that covered, and indeed I have my use case
building and working fine now.

Turns out that my problem, I *think*, was specifying relative
locations for the OpenSSL installation when configuring Curl. That
will either result in a configuration error (bad location specified
for SSL directory) or a build error (not being able to find openssl
includes, etc).

Thanks so much for the quality help received, much appreciated.
