| CMAKE_UNITY_BUILD |
| ----------------- |
| |
| This variable is used to initialize the :prop_tgt:`UNITY_BUILD` |
| property of targets when they are created. Setting it to true |
| enables batch compilation of multiple sources within each target. |
| This feature is known as a *Unity* or *Jumbo* build. |
| |
| Projects should not set this variable, it is intended as a developer |
| control to be set on the :manual:`cmake(1)` command line or other |
| equivalent methods. The developer must have the ability to enable or |
| disable unity builds according to the capabilities of their own machine |
| and compiler. |
| |
| By default, this variable is not set, which will result in unity builds |
| being disabled. |
| |
| .. note:: |
| This option currently does not work well in combination with |
| the :variable:`CMAKE_EXPORT_COMPILE_COMMANDS` variable. |
