# CXX_MODULE_HEADER_UNIT_SET_<NAME>

New in version 3.25.

Note

Experimental. Gated by `CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API`

Semicolon-separated list of files in the target's `<NAME>` C++ module header set, which has the set type `CXX_MODULE_HEADER_UNITS`. If any of the paths are relative, they are computed relative to the target's source directory. The property supports `generator expressions`.

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

See `CXX_MODULE_HEADER_UNIT_SET` for the list of files in the default C++ module header set. See `CXX_MODULE_HEADER_UNIT_SETS` for the file set names of all C++ module header sets.
