Error : while working with SQLite in windows

this is my first post. I get this error

"The processor architecture of the project being built "Any CPU" is not supported by the referenced SDK "SQLite.WP80, Version=3.8.10.2". Please consider changing the targeted processor architecture of your project (in Visual Studio this can be done through the Configuration Manager) to one of the architectures supported by the SDK: "x86, ARM". " 

while working in windows phone app and using SQLite. If I set the architecture to ARM then it will disappear but I got another error of missing "community" from namespace in SQLite.cs file. Any one can help me out? Thanks in advance.
