# INTERFACE_CXX_MODULE_HEADER_UNIT_SETS

New in version 3.25.

Note

Experimental. Gated by `CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API`

Read-only list of the target's `PUBLIC` C++ module header sets (i.e. all file sets with the type `CXX_MODULE_HEADER_UNITS`). Files listed in these C++ module header sets can be installed with `install(TARGETS)` and exported with `install(EXPORT)` and `export()`.

C++ module header sets may be defined using the `target_sources()` command `FILE_SET` option with type `CXX_MODULE_HEADER_UNITS`.

See also `CXX_MODULE_HEADER_UNIT_SETS`.
