CXX_MODULE_SET
--------------

.. versionadded:: 3.28

Semicolon-separated list of files in the target's default C++ module set,
(i.e. the file set with name and 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_<NAME>` for the list of files in other C++
module sets.
