CXX_MODULE_HEADER_UNIT_DIRS_<NAME>

Semicolon-separated list of base directories of the target's <NAME> C++ module header set, which has the set type CXX_MODULE_HEADER_UNITS. 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_DIRS for the list of base directories in the default C++ module header set. See CXX_MODULE_HEADER_UNIT_SETS for the file set names of all C++ module header sets.
