Hi,
you need to add a feature that will define what elliptic curve you want to use when you do cargo build:
currently you can choose:
cargo build --features=curvesecp256k1 for secp256k1
cargo build --features=ed25519 for ed25519
cargo build --features=curveristretto for ristretto

[omershlo]

I will add a build section in the readme file. We still have hope to avoid this way of building, (cc @tzachvk )

Hi @omershlo. Thanks, it works.
