Build Windows include runtime

Build Windows include runtime

This patch adds the Visual Studio runtime to the binaries by adding
the code generation compile flags: MT (release version) and MTd (debug
version).

More on the subject can be found under:

This helps shipping binaries and guaranteeing the runtime uses the specific
version
