Use a Clang toolchain that includes the libFuzzer runtime. Some platform-provided Clang installations do not include it; if linking fails with a missing `libclang_rt.fuzzer` library, install a complete LLVM toolchain and point `CMAKE_C_COMPILER` and `CMAKE_CXX_COMPILER` at that `clang` and `clang++`.
