CXX_MODULE_DIRS — CMake 4.3.0 Documentation

# CXX_MODULE_DIRS

Added in version 3.28.

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.
