In particular, that is `-fvisibility=hidden` on GCC/Clang (\u003e50% difference).\n\nIt's also good to turn on C++14 support if possible, since that pushes some precomputation to the compile phase. In CMake, I would just do:\n\n```\n      if (HAS_CPP14_FLAG)\n        set(CMAKE_CXX_FLAGS \"${CMAKE_CXX_FLAGS} -std=c++14\")\n      elseif (HAS_CPP11_FLAG)\n        set(CMAKE_CXX_FLAGS \"${CMAKE_CXX_FLAGS} -std=c++11\")\n      else()\n        message(FATAL_ERROR \"Unsupported compiler -- at least C++11 support is needed!\")\n      endif()\n```\n\nIs it possible to enable these flags here as well?\n","author":{"url":"https://github.com/wjakob","@type":"Person","name":"wjakob"},"datePublished":"2016-03-09T20:19:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/1/python_example/issues/1"}
