How to use NuGet-Packages with svn?

In my project there are some NuGet-Packages installed. The packages.config looks like this:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Antlr3.Runtime" version="3.5.1" targetFramework="net461" />
  <package id="FluentNHibernate" version="2.1.2" targetFramework="net461" />
  <package id="Iesi.Collections" version="4.0.4" targetFramework="net461" />
</packages>

I commited my project and updated it on another location (same computer). But now I get the following errors when I try to build the project:

It seems like, the dlls from the NuGet-Packages are missing.

Do I really have to put the dlls in the repository? Isn't NuGet supposed to get the files from some server in this case?
