CMake just detects what's available. If Python is not found in the
system, it will simply display a line of text reporting that python was
not found and then proceeds to generate the makefiles. But as `nmake
clang-test' works I guess that python already is on the PATH when `cmake
-G ..' is executed.

As for the python exception thrown from lit.cfg, I suggest filing a bug
report (or, better, fixing the bug yourself ;-)
