Help: VISIBILITY_PRESET values not documented
The documentation pages for the symbol visibility properties do not specify the supported values:
- https://cmake.org/cmake/help/v3.20/prop_tgt/LANG_VISIBILITY_PRESET.html
- https://cmake.org/cmake/help/v3.20/variable/CMAKE_LANG_VISIBILITY_PRESET.html
This is essential information and should be included.
