CMake suite maintained and supported by Kitware (kitware.com/cmake).
This is https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p1147r1.html - I don't think there is a feature test macro for this, so a fix will have to check cplusplus. However, e.g. gcc 11.2 has -std=c++23 but does not implement p1147r1, and both gcc 11.2 and gcc 11.3 set cplusplus to 202100, so I suppose both possibilities will need to be supported.
