1CMAKE_CROSS_CONFIGS 2------------------- 3 4.. versionadded:: 3.17 5 6Specifies a :ref:`semicolon-separated list <CMake Language Lists>` of 7configurations available from all ``build-<Config>.ninja`` files in the 8:generator:`Ninja Multi-Config` generator. This variable activates 9cross-config mode. Targets from each config specified in this variable can be 10built from any ``build-<Config>.ninja`` file. Custom commands will use the 11configuration native to ``build-<Config>.ninja``. If it is set to ``all``, all 12configurations from :variable:`CMAKE_CONFIGURATION_TYPES` are cross-configs. If 13it is not specified, or empty, each ``build-<Config>.ninja`` file will only 14contain build rules for its own configuration. 15 16The value of this variable must be a subset of 17:variable:`CMAKE_CONFIGURATION_TYPES`. 18
