Plugin development and usage of nuget packages

Hello I have an issue, i develop a plugin and i need to use nuget package library in my plugin. I install package but I get an error which says: Could not load file or assembly "packagename", The system cannot find the file specified.
Maybe you guys know how to solve it?

As an example, see the \Plugins\Nop.Plugin.Payments.Square\Notes.txt

...
  <!--Set this parameter to true to get the dlls copied from the NuGet cache to the output of your project.
    You need to set this parameter to true if your plugin has a nuget package
    to ensure that the dlls copied from the NuGet cache to the output of your project-->
    <CopyLocalLockFileAssemblies>false</CopyLocalLockFileAssemblies>
