Set CC, CXX, LLVM_COV, and LLVM_PROFDATA environment variables to Clang/LLVM compatible with the LLVM version used in rustc, and run cargo-llvm-cov with --include-ffi flag.

CC=<clang-path> \
CXX=<clang++-path> \
LLVM_COV=<llvm-cov-path> \
LLVM_PROFDATA=<llvm-profdata-path> \
  cargo llvm-cov --lcov --include-ffi
