[CMake] [ANNOUNCE] CMake 3.1.0-rc1 now ready for testing!

[Robert Maynard]

You can find the known compile features that can be detected at:
http://www.cmake.org/cmake/help/v3.1/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html

At the end of the compile-features manual page (
http://www.cmake.org/cmake/help/v3.1/manual/cmake-compile-features.7.html
) there is a section on how to mark a library as having conditional
support on C++11 features.

For instance, I would suppose there's one for "auto", one for move constructors/assignment operators, and one for "= delete" of default constructors/destructors et al.  These are probably the ones we'd be most interested in here, for the moment.  (Though with our requirements to support older C++ compilers, we might not actually be able to use auto, as the fallback would need the full type anyway.)  Also, is there a portability macro provided for the "= delete" feature?
