Help: Detailed compile feature version tags
The CMAKE_C_KNOWN_FEATURES
and CMAKE_CXX_KNOWN_FEATURES
documents were tagged .. versionadded:: 3.1
at the top of the file, which is true but not the complete story. Some features were added later, many much later. This MR tags each group/item with the version it first appeared in.
(It also imports the section headings from CMAKE_CXX_KNOWN_FEATURES
into CMAKE_C_KNOWN_FEATURES
, in order that the entire "High level meta features..." section can be tagged as .. versionadded:: 3.8
.)
