[lldb-dev] Running tests on windows?

Are you sure you set PYTHON_EXECUTABLE to python_d.exe? Because it's
using python.exe on your command line.
I notice you also don't have a test compiler specified. I assume you're
building with MSVC, which means you've run vcvarsall, which means that the
test suite will try to use cl.exe to compile. This also won't work, you
will need to use clang as the compiler. Since you've already built clang
as part of building LLDB, this shouldn't be too difficult, you just need to
set a CMake variable to use clang. I should probably make the CMake a
little bit smarter and attempt to find this automatically. I'll add a note
to do that soon. In the meantime set -DLLDB_TEST_COMPILER=
