Add sdk-playback option using Huawei IVS_SDK_PlaybackPlatform

[gunnxx]

Edit include file path of spdlog to its relative path and edit CMakeLists option to make it compatible with Windows

[ilhamadun]

Use -std=c++14

I see that the sdk path from Huawei is different for Linux (/lib) and Windows (/sdklib). You could use both in the find_library.

find_library(IVS_SDK_LIBRARY
    NAMES IVS_SDK
    HINTS $ENV{IVS_SDK_PATH}/lib $ENV{IVS_SDK_PATH}/sdklib
)

I'm having this error when compiling on Ubuntu.

/home/ilham/Documents/Nodeflux/sources/vms-api/modules/huawei/src/hw_ivs.cpp:291:21: error: ‘IVS_SDK_StartPlatformPlayBack’ was not declared in this scope
   int return_code = IVS_SDK_StartPlatformPlayBack(_session_id, camera_code.c_str(),
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It happened because the IVS_SDK_StartPlatformPlayBack is not exist in the sdk header for Linux. Maybe you could fix it by wrapping hwivs::HuaweiIVS::sdk_playback only for Windows.

Ok, I'll give it a try. I just knew about this compatibility thing.
By the way, the request-queue code is done, but not yet be built. I made it in request branch in my repo. Maybe you want to take a look.

[ilhamadun]

Sure. I'll take a look.

I did wrap sdk-playback for windows only and throw away some unnecessary cmake line. Already run cmake .. and make on Ubuntu and cmake .. on Windows, and both success.

Edit : just ran make .i.e build project in windows, turns out there are libs (like boost) that is not windows standard library so the path depends on where the user put it. Path have to be input manually in the project-name -> properties. Hence the edit to minimize the manually input path.
