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

[David Bakin]

Well, that's interesting.  I did clone the extra tools into
llvm\tools\clang\tools\extra.  The problem was that all of the vcxprojs for
the projects in extra were missing "additional include directories" for the
source tree's tools\clang\include and also the binary tree's
tools\clang\include.  But all other necessary include directories were
there.

The installed CMake is 3.2.1, the compiler is VS 2013 Win64, the config was
Debug, and the llvm/clang/extras are all sync'd to release_36.  LLVM and
Clang build fine (and pass unit tests).  And whatever was causing it, it
was repeatable (blowing away the build output tree, rerunning cmake-gui
with the same settings, and doing another build gave the same result.)

I guess I'll have to try again.  Are there any special cmake configuration
variables you set?  Here's my full list:

LLVM_TARGETS_TO_BUILD=X86
LLVM_ENABLE_ASSERTIONS=On
CLANG_BUILD_EXAMPLES=On
LLVM_COMPILER_JOBS=2

Thanks!

(P.S. is there a way using cmake-gui to save/write the configuration
variable settings so you can restore them the next time you want to
generate VS sln/project files instead of typing them in again?  Or,
alternatively, getting cmake-gui to emit somewhere the actual cmake command
line given the entire configuration you define with it?)
