title: CMake Install target missing when generating VS2013 build
body: <p>I'm using CMake Guid 3.0.0 and Visual Studio Express 2013 (64-bit). My CMakeLists.txt file does not generate an INSTALL target for my visual studio build. I can compile by building the ALL_BUILD project. I can then run the executable that's left in the Debug and Release folders. What do I need to add in order for the INSTALL target to build?</p>
