Rust’s clang-sys has a few ways to handle this: > libclang shared libraries will be searched for in the following directories: > the directory provided by the LIBCLANG_PATH environment variable > the bin and lib directories in the directory provided by llvm-config --libdir > the directories provided by LD_LIBRARY_PATH environment variable > a list of likely directories for the target platform (e.g., /usr/local/lib on Linux) > macOS only: the toolchain directory in the directory provided by xcode-select --print-path The other methods don’t work. LLVM still does not support pkg-config, llvm-config won’t have the libclang because we build clang and llvm separately, and LD_LIBRARY_PATH shouldn’t be messed with.

This is set by clang’s setup-hook.
