  //    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.
