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.
