title: Cannot open source file gtest/gtest.h
body: <p>I have installed <a href="https://visualstudiogallery.msdn.microsoft.com/94c02701-8043-4851-8458-34f137d10874?SRC=VSIDE" rel="nofollow">Google Test Adapter</a> in visual studio 2015 and was expecting it to automatically set include paths link to the necessary libraries. But it seems that there is some other step I am missing because I get a "cannot include gtest/gtest.h" error. If I have to manually do all this even after installing the extension, then what's the point of this extension? or am I missing something?</p>
