It is always False for targets built within the +project. + +For targets created with the ``IMPORTED`` option to +:command:`add_executable()` or :command:`add_library()` but without the +additional option ``GLOBAL`` this is False, too. However, setting this +property for such a locally ``IMPORTED`` target to True promotes that +target to global scope. This promotion can only be done in the same +directory where that ``IMPORTED`` target was created in the first place. + +Once an imported target has been made global, it cannot be changed back to +non-global. Therefore, if a project sets this property, it may only +provide a value of True. CMake will issue an error if the project tries to +set the property to a non-True value, even if the value was already False. |
