Not sure, probably an omission. "/GL" appears to be supported in
cmVS10CLFlagTable.h but not cmLocalVisualStudio7Generator.
Here's a patch
http://public.kitware.com/Bug/view.php?id=10263
P.S.
If it's not clear, CMake not supporting the WholeProgramOptimization
XML tag only affects what the Visual Studio GUI looks like and doesn't
affect the compiling of the code since the /GL shows up in the
additional options line and thus gets added to the command line when
the compiler is run.
