Adding features

This section covers adding common features to your CMake project. You’ll learn how to add a variety of options commonly needed in C++ projects, like C++11 support, as well as how to support IDEs and more.

Default build type

CMake normally does a “non-release, non debug” empty build type; if you prefer to set the default build type yourself, you can follow this recipe for the default build type modified from the Kitware blog:

set(default_build_type "Release")if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES)  message(STATUS "Setting build type to '${default_build_type}' as none was specified.")  set(CMAKE_BUILD_TYPE "${default_build_type}" CACHE      STRING "Choose the type of build." FORCE)  # Set the possible values of build type for cmake-gui  set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS    "Debug" "Release" "MinSizeRel" "RelWithDebInfo")endif()
