How to create a dummy build preset

Code
1

I am generating a number of CMakePresets.json files.
It would be convenient to be able to generate a no-op build preset.
(Rather than discovering that it will not be needed and dealing with the fall-out).

note: In the following examples these are fragments included from a driver CMakePresets.json

The problem is that the obvious options:

{
  "version": 6,
  "buildPresets": [
    {
      "name": "cb-G-iface-algorithm",
      "configurePreset": "cc-ninja",
      "configuration": "Debug",
      "inheritConfigureEnvironment": false,
      "targets": [ ]
    }
  ]
}

{
  "version": 6,
  "buildPresets": [
    {
      "name": "cb-G-iface-algorithm",
      "configurePreset": "cc-ninja",
      "configuration": "Debug",
      "inheritConfigureEnvironment": false
    }
  ]
}

Seem to build all targets.

I could make a do nothing target…

{
  "version": 6,
  "buildPresets": [
    {
      "name": "cb-G-iface-algorithm",
      "configurePreset": "cc-ninja",
      "configuration": "Debug",
      "inheritConfigureEnvironment": false,
      "targets": [ "NULL"
      ]
    }
  ]
}

…or is there some canonical way?

I believe there is an ALL target? is there a NULL or NONE target?

I added the following to my CMakeLists.txt file.

add_custom_target( NONE )

This seems to make the following work the way I want.

{
  "version": 6,
  "buildPresets": [
    {
      "name": "cb-G-iface-algorithm",
      "configurePreset": "cc-ninja",
      "configuration": "Debug",
      "inheritConfigureEnvironment": false,
      "targets": [ "NONE"  ]
    }
  ]
}
