使用CMakeLists.txt 判断编译器是否支持C++11
#将下面的内容添加到CMakeLists.txt当中
include(CheckCXXCompilerFlag) CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11) CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X) 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()
