No, you don't need to that. Actualy, as explained above, running tests
on the installed files of LLVM/Clang is not supported. Tests must be run
from the build directory (as you are doing)

So what's c:/llvmpath and c:/clangpath ?

Python must be in the PATH before you generate the makefiles, that means
before the

cmake -G "NMake Makefiles" ..\llvm -DCMAKE_BUILD_TYPE=debug

(also replace `debug' by `Debug', just in case)

You'll better install after testing succeeds.
