Optional dependency being used anyway

[Abscissa]

Maybe I'm misunderstanding something about the optional dependencies, but they don't appear to be optional. mysql-native has an optional dependency on vibe, as seen in mysqln's dub.sdl.

But if I create a fresh new directory, with these two files:

dub.sdl:

name "test"
dependency "mysql-native" version="~>1.0.0"

src/main.d:

import mysql;
void main() {}

And then run dub, dub will download vibe core, include vibe core in dub.selections.json. Using '-v' reveals that -version=Have_vibe_d_core is included in the build.

FWIW, that was with dub v1.2.0

I think I have a similar problem with dub 1.3.0

I am using vibe-d and trying to compile with botan, instead of openssl.

From what I understand botan and openssl are optional dependencies of vibe.stream. Openssl is the default optional dependency, which means it will get picked by default unless a dub.selections.json exists.

Now, regardless of what I do, the Have_openssl version gets set when compiling. That means it will pull in the openssl library when linking.

I think that dub should not set the version for an optional dependency that isn't used.
