BASE_DIRS

List of base directories of the file set. The target_sources() command sets or adds to the BASE_DIRS file set property and is the usual way to manipulate it.

Contents of BASE_DIRS may use generator expressions.

Any relative paths are considered relative to the target's source directory. No two base directories for a file set may be sub-directories of each other. This requirement must be met across all base directories added to a file set.
