Summary:                    /LTCG option does not cause LinkTimeCodeGeneration
to be set in project file
Description: 
Adding the /LTCG linker option to LINK_FLAGS or STATIC_LIBRARY_FLAGS should
cause LinkTimeCodeGeneration to be set in the project file.  For instance:

  <Tool Name="VCLinkerTool" ... LinkTimeCodeGeneration="1" />

This flag has the following forms that correspond to values 1-4 for the
LinkTimeCodeGeneration attribute:

  Option              XML Attribute Value
  ---------------------------------------
  /LTCG               1
  /LTCG:PGINSTRUMENT  2
  /LTCG:PGOPTIMIZE    3
  /LTCG:PGUPDATE      4


See: http://msdn.microsoft.com/en-us/library/xbf3tbeh.aspx

Steps to Reproduce: 
Add /LTCG to the linker (or librarian) using:

  foreach(CONFIG _RELEASE _MINSIZEREL _RELWITHDEBINFO)
    set_property(TARGET foo APPEND PROPERTY LINK_FLAGS${CONFIG} "/LTCG")
  endforeach()


  foreach(CONFIG _RELEASE _MINSIZEREL _RELWITHDEBINFO)
    set_property(TARGET bar APPEND PROPERTY STATIC_LIBRARY_FLAGS${CONFIG}
"/LTCG")
  endforeach()

Generate a Visual Studio project file.


Additional Information: 
I'm observing this on Visual Studio 2008.  This bug is similar to bug 0010263;
though that bug dealt with the compiler option and this one is about the related
linker option.
