CXX_MODULE_SET_<NAME>
---------------------

.. versionadded:: 3.28

Semicolon-separated list of files in the target's ``<NAME>`` C++ module set,
which has the set type ``CXX_MODULES``. 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_SET` for the list of files in the default C++ module
set. See :prop_tgt:`CXX_MODULE_SETS` for the file set names of all C++ module
sets.
