The underlying problem is that VS does this with a relative path:
c:\path\to\directory\with\project\file\..\..\..\relative\path\on\top\of\that\to\source.cpp
and then fails when the total string is over 250 characters or so
even though the collapsed full path would be well under the limit.
This is only a problem when CMake stores relative paths in the
project files, but we normally prefer full paths. AFAIK for
VS 8 CMake stores relative paths under only two circumstances:
(1) The unsupported option CMAKE_USE_RELATIVE_PATHS is on.
(2) The sequence of "..\" is not long enough to escape the
top-level of the build tree (CMAKE_BINARY_DIR).
Is either of these the case for your build?

FYI, the fix referenced in the thread you linked was for VS 10 only:
http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ed0075bd
There is a lot more to it as covered here:
http://www.cmake.org/Bug/view.php?id=12570
but that should not affect VS 8. There is extra trouble with VS 10
because it has one bug for relative paths and another bug for full
paths.
