[cfe-dev] Can't build clang-tools-extra using Visual Studio because of missing include directory in tools\extra project files

[Daniel Dilts]

>From my script (variables substituted), this is the set of commands that I
use (current directory is d:\llvm):

svn checkout http://llvm.org/svn/llvm-project/llvm/trunk d:/llvm/llvm
svn checkout http://llvm.org/svn/llvm-project/cfe/trunk
d:/llvm/llvm/tools/clang
svn checkout http://llvm.org/svn/llvm-project/clang-tools-extra/trunk
d:/llvm/llvm/tools/clang/tools/extra
mkdir d:\llvm\build
cd d:/llvm/build
cmake -G "Visual Studio 12" d:/llvm/llvm

I then open LLVM.sln with VS2013 and build all.  Building with revision
233933 I get error LNK1104: cannot open file 'LLVMFuzzer.lib', but that is
new (I didn't see that error yesterday).

Replacing trunk with branches/release_36 compiles with no errors or
warnings.

Note that I am building Win32/Debug.
