CXX_MODULE_HEADER_UNIT_SET_<NAME>
---------------------------------

.. versionadded:: 3.25

.. note ::

  Experimental. Gated by ``CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API``

Semicolon-separated list of files in the target's ``<NAME>`` C++ module header
set, which has the set type ``CXX_MODULE_HEADER_UNITS``. If any of the paths
are relative, they are computed relative to the target's source directory. 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:`CXX_MODULE_HEADER_UNIT_SET` for the list of files in the
default C++ module header set. See :prop_tgt:`CXX_MODULE_HEADER_UNIT_SETS` for
the file set names of all C++ module header sets.
