Enable LTCG for executables and shared libraries

Browse Source 
Enable Link Time Code Generation as some libraries are compiled using /GL (Whole Program Optimization) which requires the code generation to be delayed to link time. Not doing this will result in longer build times, as the linker has to terminate its progress if it links a library compiled with /GL, and restart this operation using /LTCG.
