# IMPORTED_GLOBAL

Indication of whether an IMPORTED target is globally visible.

The boolean value of this property is True for targets created with the `IMPORTED` `GLOBAL` options to `add_executable()` or `add_library()`. It is always False for targets built within the project.

For targets created with the `IMPORTED` option to `add_executable()` or `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.
