How can I copy the NuGet package native library files?

I have the NuGet package which managed library depends on a native library. I want to copy native dependency to the \\UnmanagedLibraries\Windows\x86\ folder and I have made the following file which is copied to the build folder:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Target Name="CopyNativeReferences">

    <Message Text="$(MSBuildThisFileDirectory) => $(OutDir)\UnmanagedLibraries\Windows\x86\"></Message>    

     <Copy SourceFiles="$(MSBuildThisFileDirectory)..\native\UnmanagedLibraries\Windows\x86\SIMDArrayInstructions.dll" 
      DestinationFolder="$(OutDir)\UnmanagedLibraries\Windows\x86\" 
      SkipUnchangedFiles="true" />

    </Target>

   <PropertyGroup>
     <AfterBuildDependsOn>
        CopyNativeReferences;
     </AfterBuildDependsOn>
    </PropertyGroup>

    <Target Name="AfterBuild" DependsOnTargets="$(AfterBuildDependsOn)"/>
</Project>

It runs fine for one package, but I have multiple NuGet packages that need to copy their native references. After I install the second package, the native references for the first package are not copied. It seems that 'AfterBuild' is overwritten with the new package.

I also changed target name and AfterBuildDependsOn to ensure that other packages do not share same names of target variables but it did not help.

How can I resolve this?

The defined property group should look like:

PropertyGroup>
 <AfterBuildDependsOn>
    $(AfterBuildDependsOn);
    CopyNativeReferences;
 </AfterBuildDependsOn>
</PropertyGroup>
