In general, you should test for specific features that you want to use, 
as they may be available on compilers that don't claim C++11 compliance 
(e.g. MSVC, g++ with -std=c++0x).

I would write a simple test program per feature and use try_compile to 
see if the feature can be used. Then use configure_file and #cmakedefine 
to generate a header file with feature test symbols that you can use in 
your real code.
