Summary:                    ExternalProject: git clone step always runs when
using "Visual Studio 10" generator
Description: 
As reported on the CMake mailing list, the git clone step always runs again on
2nd and later builds, even though the 1st build was completely successful.

This is really annoying, as it always leads to full rebuilds, because the git
clone code blows away the source tree first, and does a fresh clone when it
runs...

Steps to Reproduce: 
# CMakeLists.txt:
# ==========================================================================
cmake_minimum_required(VERSION 2.8.4)
project(SAF-ext)
include(ExternalProject)
EXTERNALPROJECT_ADD(
  SAF-ext
  GIT_REPOSITORY "git://github.com/dlrdave/SmallAndFast.git"
  GIT_TAG "5e98e304a464946dd34cb4c53eb3dd1fd348781b"
  CMAKE_ARGS
    -DSAF_INTENTIONAL_COMPILE_ERROR:BOOL=OFF
  INSTALL_COMMAND ""
  UPDATE_COMMAND ""
  )

# Save these steps to repro as a CMakeLists.txt file
# (1) Run this:
#    mkdir b1
#    cd b1
#    cmake -G "Visual Studio 10" ..
# (2) Open solution file in Visual Studio 10
# (3) Build -- allow to finish all the way
# (4) Build again
#
# Expected:
#   2nd build should build nothing as everything is up to date
#
# Actual:
#   2nd build builds evertyhing again, starting with the mkdir steps,
#   and continuing on down through git clone and all the rest...
