[lldb-dev] lldb status at windows

Fri Jan 22 12:30:51 PST 2016

Under llvm/tools also checkout lld.  So your directories should look like
this:

llvm
\-- tools
    \-- clang
    \-- lldb
    \-- lld

Then re-run cmake to generate build files again, recompile, and then it
should work.  Right now the problem is that lld-link.exe hasn't been
compiled yet.
