I just configured and my gdcmDSED.vcproj file has full paths in it.
Furthermore the build works.  Look at that file in your build tree:

 d:\Libraries\CrisalixGit\ExternalProject\ITK-build\Modules\ThirdParty\GDCM\src\gdcm\Source\DataStructureAndEncodingDefinition

with a text editor.  Do the RelativePath="" attributes have full
or relative paths in them (ignore the fact that that the name of
the attribute has the word "Relative" in it)?

Since I can't reproduce this you'll have to build your own CMake
with Debug symbols.  Then look for "RelativePath=" in the
Source/cmLocalVisualStudio7Generator.cxx file and set a breakpoint
nearby.  Run CMake with the argument

 d:\Libraries\CrisalixGit\ExternalProject\ITK-build

and trace to see why it chooses a relative path.

AFAIK the treatment of relative paths remains the same even in VS 11.
The above names are combined as

 d:\Libraries\CrisalixGit\ExternalProject\ITK-build\Modules\ThirdParty\GDCM\src\gdcm\Source\DataStructureAndEncodingDefinition\..\..\..\..\..\..\..\..\ITK\Modules\ThirdParty\GDCM\src\gdcm\Source\DataStructureAndEncodingDefinition\gdcmVR16ExplicitDataElement.cxx

which is 260 characters long, over the 250-ish limit.
