# <LANG>_VISIBILITY_PRESET

Value for symbol visibility compile flags

The `<LANG>_VISIBILITY_PRESET` property determines the value passed in a visibility related compile option, such as `-fvisibility=` for `<LANG>`. This property affects compilation in sources of all types of targets (subject to policy `CMP0063`).

This property is initialized by the value of the `CMAKE_<LANG>_VISIBILITY_PRESET` variable if it is set when a target is created.
