[Boost-users] Determine if boost was compiled with c++11

Hello, My project uses cmake, gcc with c++11 support, and boost compiled libraries. Apparently my project must use only boost libraries that were created with c++11. The consequences of not doing this are random crashes. Is there a way I can determine whether or not boost was compiled with a c++11 compiler? I would like to verify, at configure time, that a c++11 version of boost is being used. Thank you, Chris
