CMAKE_DEFAULT_CONFIGS --------------------- .. versionadded:: 3.17 Specifies a :ref:`semicolon-separated list ` of configurations to build for a target in ``build.ninja`` if no ``:`` suffix is specified in the :generator:`Ninja Multi-Config` generator. If it is set to ``all``, all configurations from :variable:`CMAKE_CROSS_CONFIGS` are used. If it is not specified, it defaults to :variable:`CMAKE_DEFAULT_BUILD_TYPE`. For example, if you set :variable:`CMAKE_DEFAULT_BUILD_TYPE` to ``Release``, but set :variable:`CMAKE_DEFAULT_CONFIGS` to ``Debug`` or ``all``, all ```` aliases in ``build.ninja`` will resolve to ``:Debug`` or ``:all``, but custom commands will still use the ``Release`` configuration. The value of this variable must be a subset of :variable:`CMAKE_CROSS_CONFIGS` or be the same as :variable:`CMAKE_DEFAULT_BUILD_TYPE`. It must not be specified if :variable:`CMAKE_DEFAULT_BUILD_TYPE` or :variable:`CMAKE_CROSS_CONFIGS` is not used.
