cargo vcpkg build fails if vcpkg.json file is present as well

[SwishSwushPow]

Edit: Of course I find the reason for it as soon as I open an issue. When a vcpkg.json file is present in the same folder as the Cargo.toml, the cargo vcpkg build process fails. I just renamed the manifest file to _vcpkg.json and now the command runs through without issue. I've updated the issue title to reflect this. Maybe it's worth to discuss this behavior.

Hey everyone 👋
I wanted to try out cargo vcpkg yet I fail to get it working with a small example project. I get the following output:

cargo vcpkg build
     Cloning https://github.com/microsoft/vcpkg
    Checkout branch master
     Pulling branch master
   Compiling vcpkg
  Installing sqlite3
-- stdout --

-- stderr --

cargo-vcpkg: failed

This is my Cargo.toml:

[package]
name = "vcpkg_sqlite3"
version = "0.1.0"
edition = "2018"

[build-dependencies]
vcpkg = { git = "https://github.com/GiGainfosystems/vcpkg-rs", branch = "manifest-mode" }

[dependencies]
rusqlite = "0.25.3"

[package.metadata.vcpkg]
git = "https://github.com/microsoft/vcpkg"
branch = "master"
dependencies = ["sqlite3"]

I am on macOS Big Sur (11.5.2) and I can try to provide information that could also be helpful.

Best regards,
Björn

When I was running cargo vcpkg -v build on a similar setup I was getting

error: In manifest mode, `vcpkg install` does not support individual package arguments.

And then I removed what would be your dependencies = ["sqlite3"] line from the Cargo.toml and the install succeeded.

I'm curious if you would get the same, perhaps this issue is just for a better error message in manifest mode 🤔
