Hi All,

  When we try to build vide.d using ldc (dub build) we are getting the below error, openssl is already been installed (OpenSSL 1.0.2j-fips  26 Sep 2016), hence request your help on the same.

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"
    },
```

See: https://github.com/vibe-d/vibe.d/blob/70b50fdb9cd4144f1a5007b36e6ac39d4731c140/tls/dub.sdl#L99-L103
