CMAKE: check for c++11 support #63

Closed mgerhardy closed 8 years ago

mgerhardy commented 8 years ago

On Ubuntu 12.04 a very old gcc is available that doesn't support c++11 - we should add a check here:

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(FATAL_ERROR "Compiler ${CMAKE_CXX_COMPILER} has no C++11 support.")
endif()
