Visual studio 2010 missing BI 2010 (SSDT 2010)
Visual Studio 2010 is no longer supported for SQL Server Business Intelligence tools. You will not find a download link unless Google or some other site might have cached it somewhere.

You will need to download Visual Studio 2012 SSDT-BI or 2013, these support BI projects for SQL Server 2012 and 2014 respectively.
