We keep all the project files (VS 6, VS 2003 and VS 2008) in one common directory that is separate from the source tree.  Based on what I read it looks like CMake expects the CMakeLists.txt to exist in the same directory as the source.

CMake will deposit its generated .vcproj/.sln files in
CMAKE_CURRENT_BINARY_DIR. It is a best practice to have your BINARY_DIR
separate from your SOURCE_DIR (where CMakeLists.txt resides) -- this is
what is referred to as an "out-of-source build".
