Summary0011313: CMake cannot find files specified with extended-length paths.
DescriptionCMake 2.6.x and 2.8.0 and Visual Studio 2005 seem to work with extended-length paths. e.g.,

add_library( name //?/C:/foo/bar/file.cpp )

but CMake 2.8.2 reports:

CMake Error in C:/foo/bar/CMakeLists.txt: Cannot find source file "file.cpp".

Extended-length path support needed to support deep hierarchies.
Steps To Reproduce
Additional Information"To specify an extended-length path, use the "\\?\" prefix."

It looks like kwsys/SystemTools.cxx is changing "//?/C:/foo/bar/baz.cpp" to "/?//". This could be a workaround:

kwsys_stl::string SystemTools::GetActualCaseForPath(const char* p)
{
 #ifndef _WIN32
   return p;
 #else
+ if( 0 == strncmp( p, "//?/", 4 ) ) {
+ return p;
+ }
