// This follows the steps listed here:
// http://blogs.msdn.com/zakramer/archive/2006/05/22/603558.aspx
// 1. Compiler compiles the application and generates the *.obj files.
// 2. An empty manifest file is generated if this is a clean build and if
// not the previous one is reused.
// 3. The resource compiler (rc.exe) compiles the *.manifest file to a
// *.res file.
// 4. Linker generates the binary (EXE or DLL) with the /incremental
// switch and embeds the dummy manifest file. The linker also generates
// the real manifest file based on the binaries that your binary depends
// on.
// 5. The manifest tool (mt.exe) is then used to generate the final
// manifest.
// If the final manifest is changed, then 6 and 7 are run, if not
// they are skipped, and it is done.
// 6. The resource compiler is invoked one more time.
// 7. Finally, the Linker does another incremental link, but since the
// only thing that has changed is the *.res file that contains the
// manifest it is a short link.
