Which Linux distribution ? Which version of Vibe.d ?
A recent enough Vibe.d should detect OpenSSL based on 1) 
pkg-config 2) the openssl binary. Make sure you have the 
development version of OpenSSL installed.
Additionally, v1.0.2 is quite old (and subject to security 
issues), so you might want consider upgrading. But even with that 
version, it should work.
You can force the usage of a certain configuration using:

```
     "dependencies": {
         "vibe-d": "~>0.9",
         "vibe-d:tls": "*"
     },
     "subConfigurations": {
         "vibe-d:tls": "openssl-1.0"
     },
```
