How to specify an IDE build tool generator in CLI2?

Mbed CLI
1

The mbed migration guide from CLI1 to CLI2 says:

Repository management

…

The subcommand mbed-cli export (generate an IDE project) is deprecated. Use CMake generators instead. While CMake supports many generators, including many not supported by Mbed CLI 1, not all of Mbed CLI 1’s exporters have replacements available yet. The available project generators are listed below.

However, I couldn’t find any CLI2 command enabling to trigger an ID build tool generator.

The CMake commnad

cmake -S . -B ./cmake_build <build path> 'QtCreator - Ninja'

fails with

CMake Error: Could not create named generator QtCreator - Ninja

Generators
  Green Hills MULTI            = Generates Green Hills MULTI files
                                 (experimental, work-in-progress).
* Unix Makefiles               = Generates standard UNIX makefiles.
  Ninja                        = Generates build.ninja files.
  Ninja Multi-Config           = Generates build-<Config>.ninja files.
  Watcom WMake                 = Generates Watcom WMake makefiles.
  CodeBlocks - Ninja           = Generates CodeBlocks project files.
  CodeBlocks - Unix Makefiles  = Generates CodeBlocks project files.
  CodeLite - Ninja             = Generates CodeLite project files.
  CodeLite - Unix Makefiles    = Generates CodeLite project files.
  Eclipse CDT4 - Ninja         = Generates Eclipse CDT 4.0 project files.
  Eclipse CDT4 - Unix Makefiles= Generates Eclipse CDT 4.0 project files.
  Kate - Ninja                 = Generates Kate project files.
  Kate - Unix Makefiles        = Generates Kate project files.
  Sublime Text 2 - Ninja       = Generates Sublime Text 2 project files.
  Sublime Text 2 - Unix Makefiles
                               = Generates Sublime Text 2 project files.

  • How can I specify an already available project generator (for example the Qt Creator) in CLI2?

  • Is there an undocumented CLI2 command?
