HEADER_SETS
-----------

.. versionadded:: 3.23

List of the target's ``PRIVATE`` and ``PUBLIC`` header sets (i.e. all
file sets with the type ``HEADERS``). Files listed in these file sets
are treated as source files for the purpose of IDE integration.
The files also have their :prop_sf:`HEADER_FILE_ONLY` property set to
``TRUE``.

This property is normally only set by :command:`target_sources(FILE_SET)`
rather than being manipulated directly.

See also :prop_tgt:`HEADER_SET_<NAME>`, :prop_tgt:`HEADER_SET` and
:prop_tgt:`INTERFACE_HEADER_SETS`.
