The latest changes on the branch should work *IF* you create a file named
"System.Data.SQLite.Core.targets.user" in the same directories as the
MSBuild targets file, containing:

<Project
  <PropertyGroup>
    <ContentSQLiteInteropFiles>true</ContentSQLiteInteropFiles>
    <CopySQLiteInteropFiles>false</CopySQLiteInteropFiles>
    <CleanSQLiteInteropFiles>false</CleanSQLiteInteropFiles>
    <CollectSQLiteInteropFiles>false</CollectSQLiteInteropFiles>
  </PropertyGroup>
</Project>
