Build failed at very beginning:

source/lldb.cpp:19:10: fatal error: 'clang/Basic/Version.h' file not found

But there are much more places which depends on Clang headers (AST, Basic).

I build LLVM/Clang/ect with LLVM_INSTALL_TOOLCHAIN_ONLY=ON, so source
and build directories are needed for headers and libraries. I try to
save disc space for final installation and we don't use LLVM/Clang
headers/libraries internally, so source and build directories were
good enough for us.
