I'm trying to build current trunk of clang on OS X 10.10.5.

# clang++ --version
Apple LLVM version 7.0.0 (clang-700.0.72)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

I'm building using the following commands:

cmake \
    -G "Ninja" \
    -DCMAKE_BUILD_TYPE:STRING="RelWithDebInfo" \
    -DCMAKE_INSTALL_PREFIX:PATH="/Users/tobias/Development/llvm/llvm_prefix" \
    -DCMAKE_CXX_FLAGS:STRING="-DLLVM_ENABLE_DUMP" \
    ../llvm
ninja -j 4
ninja install

When building a minimal c++ example with the just installed clang compiler it
won't find the STL headers. They are usually located somewhere inside XCode.app.

> cat foo.cpp
#include <iostream>

int main() {
    return 0;
}
> clang++ -v -o foo foo.cpp
