Based on the .so extensions in your mail I take it you'll use shared OpenSSL
Then it doesn't matter which lib you build against as then you'll get to use
the ones that are installed on the actual machine that you _run_ the program
on as the libs are loaded run-time.
The only thing that is important is that you build with a lib that has the
same ABI as the one you run with later.

The configure is written to accept --with-ssl=PATH and try that given path
first, so if you just point out the ssl path like that it should work fine.
You can always load config.log after configure has run to verify that all
details and paths in the OpenSSL check looks fine.
