| HEADER_DIRS | |
| ----------- | |
| .. versionadded:: 3.23 | |
| Semicolon-separated list of base directories of the target's default | |
| header set (i.e. the file set with name and type ``HEADERS``). The property | |
| supports :manual:`generator expressions <cmake-generator-expressions(7)>`. | |
| This property is normally only set by :command:`target_sources(FILE_SET)` | |
| rather than being manipulated directly. | |
| See :prop_tgt:`HEADER_DIRS_<NAME>` for the list of base directories in | |
| other header sets. |
