# OBJECT_DEPENDS

Additional files on which a compiled object file depends.

Specifies a ;-list of full-paths to files on which any object files compiled from this source file depend. On Makefile Generators and the `Ninja` generator an object file will be recompiled if any of the named files is newer than it. Visual Studio Generators and the `Xcode` generator cannot implement such compilation dependencies.

This property need not be used to specify the dependency of a source file on a generated header file that it includes. Although the property was originally introduced for this purpose, it is no longer necessary. If the generated header file is created by a custom command in the same target as the source file, the automatic dependency scanning process will recognize the dependency. If the generated header file is created by another target, an inter-target dependency should be created with the `add_dependencies()` command (if one does not already exist due to linking relationships).
