CMake offers an even finer level of control over the language standard by introducing the concept of compile features. These are features introduced by the language standard, such as variadic templates and lambdas in C++11, and automatic return type deduction in C++14. You can ask for certain features to be available for specific targets with the target_compile_features() command and CMake will automatically set the correct compiler flag for the standard. It is also possible to have CMake generate compatibility headers for optional compiler features.
We recommend reading the online documentation for cmake-compile-features to get a complete overview of how CMake can handle compile features and language standards: https://cmake.org/cmake/help/latest/manual/cmake-compile-features.7.html ...
