Can't use optional dependencies in a build script

[gkoz]

When an optional dependency is enabled via --features bar_feat the build script is built without --extern bar=... and can't import the bar crate.

[project]
name = "foo"
version = "0.5.0"
build = "build.rs"

[features]
bar_feat = ["bar"]

[dependencies.bar]
path = "bar"
optional = true

A failing test.

This was supposed to be a workaround for #1581... 😦

[gkoz]

Oops, I might've misunderstood something. Does the build script not get access to any of the normal dependencies?

[alexcrichton]

Ah yes this is intended behavior, build scripts don't have access to normal dependencies. I believe you can have an optional build-dependencies entry, however, though.

[gkoz]

Yep, that's it.
