| ADDITIONAL_CLEAN_FILES |
| ---------------------- |
| |
| .. versionadded:: 3.15 |
| |
| A :ref:`semicolon-separated list <CMake Language Lists>` of files or |
| directories that will be removed as a part of the global ``clean`` target. |
| It is useful for specifying generated files or directories that are used by |
| multiple targets or by CMake itself, or that are generated in ways which cannot |
| be captured as outputs or byproducts of custom commands. |
| |
| If an additional clean file is specific to a single target only, then the |
| :prop_tgt:`ADDITIONAL_CLEAN_FILES` target property would usually be a better |
| choice than this directory property. |
| |
| Relative paths are allowed and are interpreted relative to the |
| current binary directory. |
| |
| Contents of ``ADDITIONAL_CLEAN_FILES`` may use |
| :manual:`generator expressions <cmake-generator-expressions(7)>`. |
| |
| This property only works for the :generator:`Ninja` and the Makefile |
| generators. It is ignored by other generators. |
