That last question is the correct guess. /etc/ld.so.conf will tell
you what your default paths are (and if it includes other files, so
will they).
The are two ways to handle this. One is with the usual setting of
LD_LIBRARY_PATH:
$ LD_LIBRARY_PATH=`pwd` ldd libssl.so.1.0.0
The other is, when you compile your application, to use
-Wl,-rpath,/prefix/openssl/lib
Incidently, I think that when you do this, you'll find that it finds
your libraries all right:
$ ldd /prefix/openssl/bin/openssl
The reason is that the application has been built with said -rpath
A last note: with OpenSSL 1.1.0 and on, rpath isn't automatically
applied to the openssl application, but is a matter of extra
configuration arguments.
Cheers,
Richard
