CMake 3.0.0 will have a features support where you specify the features you 
require, and an error is reported at CMake time if the in-use compiler does 
not support the feature (and CMake will add the required -std flag if 
needed).

 target_compiler_features(foo 
   # 'PUBLIC' means the foo target requires the following features in its 
   # implementation and its interface:
   PUBLIC 
     cxx_variadic_templates
     cxx_override_control
     cxx_lambdas
 )

The names of features are chosen correspond with clang features where it 
makes sense:
