redfish 4b228dd356 cmake: epee: use var from FindOpenSSL.cmake
This fixes linking when path to openssl
is defined manually:
cmake -DOPENSSL_ROOT_DIR='/usr/include/openssl-1.0;/usr/lib/openssl-1.0' ...

This is useful for building with OpenSSL v1.0
when default system installation is v1.1.

The linking error is undefined SSL_load_error_strings symbol.
This is due to -L /usr/lib/openssl-1.0 not making it onto
the linkline (so -lssl pulls in the default system openssl).
