| CMAKE_CROSS_CONFIGS |
| ------------------- |
| |
| .. versionadded:: 3.17 |
| |
| Specifies a :ref:`semicolon-separated list <CMake Language Lists>` of |
| configurations available from all ``build-<Config>.ninja`` files in the |
| :generator:`Ninja Multi-Config` generator. This variable activates |
| cross-config mode. Targets from each config specified in this variable can be |
| built from any ``build-<Config>.ninja`` file. Custom commands will use the |
| configuration native to ``build-<Config>.ninja``. If it is set to ``all``, all |
| configurations from :variable:`CMAKE_CONFIGURATION_TYPES` are cross-configs. If |
| it is not specified, or empty, each ``build-<Config>.ninja`` file will only |
| contain build rules for its own configuration. |
| |
| The value of this variable must be a subset of |
| :variable:`CMAKE_CONFIGURATION_TYPES`. |
