How to create nuget package for native C++ - c++

Question

I want to publish package about sdl_mixer, it's a native package. I did as tutorial said. I put .dll .hand .lib files into package content, but the final package didn't work. So what is right way to create c++ nuget package?
Another question: I found in nuget, most native c++ package are published in two packages, for example:
sdl2_ttf.v140
sdl2_ttf.v140.redist
What is difference between those two files? And how can I publish my packages like that?
Update:
I followed the tutorial on how to publish native packages. I have written the following autopkg file
nuget{
nuspec {
id = MySdl_mixer;
version :2.0.0.0;
title: sdl mixer;
authors: { Sam Lantinga, Stephane Peter, Ryan Gordon};
owners: {spartawhy117};
licenseUrl: "http://libsdl.org/license.php";
projectUrl: "http://libsdl.org/index.php";
iconUrl:"";
requireLicenseAcceptance:false;
summary:Nothing;
description: #"SDL_mixer is a sample multi-channel audio mixer library....
";
releaseNotes: "Release of C++ ";
copyright:Copyright 2015;
tags: {v140 ,sdl_mixer , native, CoApp };
};
files {
#defines {
Include = include\;
Bin = bin64\;
Lib = lib64\;
}
include:{"${Include}*"};
[x64,v140,debug,desktop]{
lib: ${Lib}SDL2_mixer.lib;
bin: ${Bin}SDL2_mixer.dll；
}
[x64,v140,release,desktop]{
lib: ${Lib}SDL2_mixer.lib;
bin: ${Bin}SDL2_mixer.dll；
}
};
targets {
Defines += HAS_SDLMIXER;
};
}
Running the command Write-NuGetPackage .\sdl_mixer.autopkg returns an error unexpected input of the end. What is the problem here?

Answer 1

I searched around for days until I found there is really no help out there on the internet at all. I did managed to piece together how to do it, and through trial and error got it working well. Which I have documented here:
https://digitalhouseblog.wordpress.com/2019/08/22/how-to-make-a-nuget-package-for-c/
But I'll summarize here anyways:
Gather or stage your native library files into a folder of your
choosing.
Create a *.nuspec file in that folder.
Edit the *.nuspec file to include the files you want to include in your package.
Create a *.props file
Call nuget pack to create the package.
Push the nuget package to a feed somewhere.
Create a packages.config file.
Edit the visual studio project file to import the *.props file
Notice that the nuget tools inside the visual studio IDE are NEVER used. You have to do a LOT manually. See the link for full details and explanations.

You can use CoApp PowerShell tools to create the Native Nuget packages easily.
Creating Native Packages
If you’re interested in publishing your
native libraries via NuGet, you can choose to create the NuGet
packages manually. However, there’s an easier way--the CoApp project
volunteered to write C++ oriented tools to create NuGet packages, and
they have released a beta version of their tools. These tools simplify
the process of generating the MSBuild files and NuGet packages from
existing header and library files--you just need to create a
configuration script to describe the contents of the package and then
run the tools to generate the NuGet package.
Refer to this link for more detailed information: Support for Native Projects.

If you want to do this from Visual Studio C++ using a Visual Studio Solution and projects.
Look at my answer here.
