How to enable crate features per-platform in Cargo.toml?

How do I enable crate features per-platform in a Cargo.toml configuration? I've tried two methods, neither of which work.

Method 1:

[target.'cfg(windows)'.dependencies.rusqlite]
version = "0.19.0"
features = ["bundled"]

[target.'cfg(unix)'.dependencies.rusqlite] # same behavior with cfg(not(windows))
version = "0.19.0"

Method 2:

[target.'cfg(windows)'.dependencies]
rusqlite = { version = "0.19.0", features = ["bundled"] }

[target.'cfg(unix)'.dependencies]
rusqlite = { version = "0.19.0" }

I'm trying to use the 'bundled' feature only on Windows platforms, but regardless of which way I try to configure cargo it always adds the 'bundled' feature when building on an Ubuntu system.

Is it possible to enable features only on one platform?

Unfortunately the features system of Cargo is, right now, very very limited and makes working on cross platform applications very painful – Denys Séguret

No, it is not possible, due to Cargo issue #1197.
