I found it. CMake actually is preserving the path as "/test" until
the make tool re-runs it with the "-H\test" option. Then the same
code path that causes just "cmake ... \test" to fail gets hit. The
code assumed that paths with a single leading slash were always
UNIX-style paths with forward slashes.
Please try the patch below against v2.8.2 on your real test case.
It works for me with the toy case you posted. I don't know how
this would have worked for you with earlier CMake versions. This
code has not changed in a long time.

P.S. I don't know what I was smokin' earlier when I claimed that
"/test" is not valid. CMake uses forward slashes for all its paths
internally even on Windows, and I also know it's okay to use an
implied current drive letter. My bad.
