8 Experimental. Gated by ``CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API``
10 Semicolon-separated list of base directories of the target's ``<NAME>`` C++
11 module set, which has the set type ``CXX_MODULES``. The property supports
12 :manual:`generator expressions <cmake-generator-expressions(7)>`.
14 This property is normally only set by :command:`target_sources(FILE_SET)`
15 rather than being manipulated directly.
17 See :prop_tgt:`CXX_MODULE_DIRS` for the list of base directories in the
18 default C++ module set. See :prop_tgt:`CXX_MODULE_SETS` for the file set names
19 of all C++ module sets.
