You are correct. It's not a problem with CMake or lit; c-index-test uses the libclang shared library, which expects to find "clang" in ../bin/clang relatively to itself. It's actually a holdover from an old, to-be-deprecated API that implements some of the Clang C API via invocations of the clang binary.
