How to exclude referenced content folder from nuget package

Question

I have three referenced content folders from another project in my .csproj file:

 <Content Include="..\infrastructure\Content\**\*.*">
      <Link>Infrastructure\Content\%(RecursiveDir)%(FileName)%(Extension)</Link>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
    <Content Include="..\infrastructure\fonts\**\*.*">
      <Link>Infrastructure\fonts\%(RecursiveDir)%(FileName)%(Extension)</Link>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
    <Content Include="..\infrastructure\Scripts\**\*.*">
      <Link>Infrastructure\Scripts\%(RecursiveDir)%(FileName)%(Extension)</Link>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>

I want to create a nuget package from my project without the included content files. I have tried this command:

nuget pack sampleproj.csproj -Exclude ../infrastructure/** -NoDefaultExcludes -IncludeReferencedProjects -Verbosity detailed

But it includes the above files. I have also tried these arguments for -Exclude with no success:

infrastructure/**
../../infrastructure/**
bin/infrastructure/**

When I use **/infrastructure/** it works, but also excludes some files that I need them to be packaged.

How can I exclude referenced content files?

P.S: in my .nuspc file I have only one file element: <file src="cassette-cache\**" target="Content" /> .
