# CXX_MODULE_DIRS_<NAME>

Added in version 3.28.

Semicolon-separated list of base directories of the target's `<NAME>` C++ module set, which has the set type `CXX_MODULES`. The property supports `generator expressions`.

This property is normally only set by `target_sources(FILE_SET)` rather than being manipulated directly.

See `CXX_MODULE_DIRS` for the list of base directories in the default C++ module set. See `CXX_MODULE_SETS` for the file set names of all C++ module sets.
