CXX_MODULE_DIRS

.. versionadded:: 3.28

Semicolon-separated list of base directories of the target's default C++ module set (i.e. the file set with name and type CXX_MODULES). 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_DIRS_<NAME> for the list of base directories in other C++ module sets.
