[openssl-dev] Switch or option for out-of-tree operations?

[Richard Levitte]

I suggest you read the docs, such as INSTALL.  If you go down a bit,
you'll find the section "Installation in Detail", and a little bit
further, you'll find "1c. Configure OpenSSL for building outside of
the source tree."

Cheers,
Richard
