See :manual:`cmake-buildsystem(7)` for more on transitive behavior of build properties and usage requirements. +Requiring Language Standards +---------------------------- + +In projects that use a large number of commonly available features from +a particular language standard (e.g. C++ 11) one may specify a +meta-feature (e.g. ``cxx_std_11``) that requires use of a compiler mode +aware of that standard. This is simpler than specifying all the +features individually, but does not guarantee the existence of any +particular feature. Diagnosis of use of unsupported features will be +delayed until compile time. + +For example, if C++ 11 features are used extensively in a project's +header files, then clients must use a compiler mode aware of C++ 11 +or above. This can be requested with the code: + +.. code-block:: cmake + + target_compile_features(mylib PUBLIC cxx_std_11) + +In this example, CMake will ensure the compiler is invoked in a mode +that is aware of C++ 11 (or above), adding flags such as +``-std=gnu++11`` if necessary. This applies to sources within ``mylib`` +as well as any dependents (that may include headers from ``mylib``). + +Availability of Compiler Extensions +----------------------------------- + Because the :prop_tgt:`CXX_EXTENSIONS` target property is ``ON`` by default, CMake uses extended variants of language dialects by default, such as ``-std=gnu++11`` instead of ``-std=c++11``.
