# CXX_MODULE_DIRS

New in version 3.25.

Note

Experimental. Gated by `CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API`

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 `generator expressions`.

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

See `CXX_MODULE_DIRS_<NAME>` for the list of base directories in other C++ module sets.
