"the canonical cmake way" good question! It turns out that, providing another
hint for `find_package(Clang ...)` does exactly that: it sets Clang_DIR to the
first path where it found Clang. If we do not attach great importance to the
status message, we could do:
find_package(LLVM REQUIRED CONFIG HINTS ${LLVM_DIR} NO_CMAKE_FIND_ROOT_PATH)
find_package(Clang REQUIRED CONFIG HINTS ${Clang_DIR} ${LLVM_DIR}/../clang
NO_CMAKE_FIND_ROOT_PATH)
# Clang_DIR is defined now even if the ${LLVM_DIR}/../clang fallback was used
