[openssl-users] How to invoke RPATH settings?

[Jeffrey Walton]

OpenSSL has support for RPATHs.

How do we invoke the support? Configure and --openssldir or --prefix
does not do it.

Should there be an --rpath option to Configure make this clear and easy?

./Configure linux-x86_64 shared no-ssl2 no-ssl3 no-comp
--openssldir=/usr/local/ssl --prefix=/usr/local/ssl
make depend
make
...
$ ldd ./libssl.so
    linux-vdso.so.1 =>  (0x00007fffa14ef000)
    libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0
