  add_subdirectory(path/to/clang-closure
    ${CMAKE_CURRENT_BINARY_DIR}/clang-closure
    )
  

  to path/to/clang-tools-extra/CMakeLists.txt, and

  add_subdirectory(path/to/clang-closure/unittests
    ${CMAKE_CURRENT_BINARY_DIR}/clang-closure
    )
  

  to path/to/clang-tools-extra/unittests/CMakeLists.txt.
