| CMAKE_UNITY_BUILD | |
| ----------------- | |
| Initializes the :prop_tgt:`UNITY_BUILD` target property on targets | |
| as they are created. Set to ``ON`` to batch compilation of multiple | |
| sources within each target. This feature is known as "Unity build", | |
| or "Jumbo build". By default this variable is not set and so does | |
| not enable unity builds on targets. | |
| .. note:: | |
| This option currently does not work well in combination with | |
| the :variable:`CMAKE_EXPORT_COMPILE_COMMANDS` variable. |
