because it uses overrides and the `versions` feature flag is disabled.

Hi， everyone , i want to use vcpkg install the library of uwebsocket, when i tried to install its older repo(version v0.14.0 or 14.0.0), i changed the vcpkg.json file as the example displayed :

{
  "name": "uwebsockets",
  "version": "14.0.0.0",
  "description": "Simple, secure & standards compliant web I/O for the most demanding of applications",
  "homepage": "https://github.com/uWebSockets/uWebSockets",
  "dependencies": [
    "usockets",
    "zlib"
  ],
  "overrides": [
    {
      "name": "uwebsockets",
      "version": "14.0.0"
    }
  ]
}

however, when i put .\vcpkg install uwebsockets:x64-windows in the terminate, the error occurred as follows: Computing installation plan... Parsing manifest failed: F:\vcpkg-master\vcpkg-master\ports\uwebsockets was rejected because it uses overrides and the versions feature flag is disabled. This can be fixed by removing "overrides". See vcpkg help versioning for more information. Note: Updating vcpkg by rerunning bootstrap-vcpkg may resolve this failure.

Anyhelp will be very appreciated!!!!

Hi @sainttelant

You need to enable the versions feature flag. There are a couple of ways to do this on Windows.

The easiest one is to create an environment variable VCPKG_FEATURE_FLAGS with versions as its value. Other ways to do it are described in the versioning announcement blog post.

You do need to set the builtin-baseline which can be set to the latest commit of vcpkg.
