After looking at the CMake scripts related to testing it seems to me
that you don't need to execute `make check' for generating the
confiration files for lit.

Are you trying to test an installed Clang or LLVM? (that's not
supported) Is the python interpreter found when you configure your build
directory with cmake?

Those c:/llvmpath and c:/clangpath on your command looks suspicious to
me.
