Manifest release profile warning
Created by: ascjones
While testing out https://github.com/paritytech/cargo-contract/pull/174, I received the following warning while building sub contracts in the workspace:
This might be important because cargo-contract
manually sets some preferred defaults for building release contracts.
We should check that they are set in the root workspace manifest, and that they still have the desired effect for sub contracts. Also we should not modify the sub contracts manifest if they have no effect there and avoid the warning.
