一， 通用范式
cmake_minimum_required(VERSION 2.8)
project (hello_cpp11)
# 检查c++编译器标志，设置c++11支持变量include(CheckCXXCompilerFlag)CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)
# 使用变量设置编译标志if(COMPILER_SUPPORTS_CXX11) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")elseif(COMPILER_SUPPORTS_CXX0X) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")else() message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")endif()
add_executable(hello_cpp11 main.cpp)
二， 使用CMAKE_CXX_STANDARD变量
cmake 3.1版本后才有的特性
cmake_minimum_required(VERSION 3.1)
project (hello_cpp11)
# 设置C++标准为 C++ 11set(CMAKE_CXX_STANDARD 11)
add_executable(hello_cpp11 main.cpp)
三， 使用自动推断方式
cmake 3.1版本后才有的特性
cmake_minimum_required(VERSION 3.1)
project (hello_cpp11)
add_executable(hello_cpp11 main.cpp)
# 使用自动推断的方式选择合适的c++标准target_compile_features(hello_cpp11 PUBLIC cxx_auto_type)
message("List of compile features: ${CMAKE_CXX_COMPILE_FEATURES}")
