msvcprtd.lib(MSVCP100D.dll) : error LNK2005: already defined in gtestd.lib(gtest.obj)

This error occurs when the C/C++ Code Generation Runtime Library in gtest is defined differently from testing code using it.  The gtest project was defined as MTd (Multi-threaded Debug) and the testing project defined as MDd (Multi-threaded DLL).

Fix:  Changed the testing project to use MTd.  From the Property Pages select Configuration Properties ==> C/C++ ==> Code Generation ==> Runtime Library ==> Multi-threaded (/MT).
