declare_program! macro panic with derive may only be applied to structs, enums and unions

[yubin-prestolabs]

Problem

When using the declare_program!() to generate client sdk from idl file, I see the following error:

error[E0774]: `derive` may only be applied to `struct`s, `enum`s and `union`s
 --> src/trydeclare.rs:5:1
  |
5 | declare_program!(ammv3);
  | ^^^^^^^^^^^^^^^^^^^^^^^
  | |
  | not applicable here
  | not a `struct`, `enum` or `union`
  |
  = note: this error originates in the macro `declare_program` (in Nightly builds, run with -Z macro-backtrace for more info)

Specifically, I am using the idl file from raydium-clmm program, https://github.com/raydium-io/raydium-idl/blob/master/raydium_clmm/amm_v3.json

anchor version, rust version, etc

How to reproduce

1. create a rust mod with the following:

pub mod trydeclare {
use anchor_lang::declare_program;
use anchor_lang::declare_id;
declare_id!("CAMMCzo5YL8w4VFF8KVHrK22GGUsp5VTaW7grrKgrWqK");
declare_program!(ammv3);
}

2. create the ammv3.json from the json file above, adding the metadata field:

{
    "metadata": {
        "address": "CAMMCzo5YL8w4VFF8KVHrK22GGUsp5VTaW7grrKgrWqK"
    },
  "version": "0.1.0",
  "name": "amm_v3",
  /// ... 
}

3. run cargo build or compile any other way. You will then see the error above.
