[cfe-dev] Running regression tests from Windows command line

[Alistair Low]

Thanks, that works now. I don't think I had Python in the path the last 
time I ran CMake. I get Access Denied errors now when lit tries to run a 
test but I'm sure that's a Windows problem that I can solve easily.

Thanks for all the help,
Alistair
