<div>Hi Yaron,<br>
<br>
Just tried creating an sln with latest llvm/clang/lldb using the
Visual Studio 12 Win64 Generator and had no cmake errors. This is
just with default configuration, target X86 with llvm asserts
enabled. Do you have any other non-standard options?<br>
<br>
Cheers,<div class="im"><br>
