Как получить llvm IR зависимость для построения

Question

Я пытаюсь собрать какую-то ветку blender на Ubuntu 18.04, и мне нужно получить llvm / IR / IRBuilder.h

Я установил sudo apt-get install clang-5.0 lldb-5.0 lld-5.0 из https://apt.llvm.org/но это не помогает.

Как я могу получить эту зависимость?

UPD У меня небольшой прогресс:

Я запускаю это в папке сборки

cmake -DLLVM_INCLUDE_DIRS=/usr/wherever/the/llvm/includes/are/on/your/system/ . 

Это останавливает меня на следующем шаге:
