Systems like Guix (and maybe Nix) set the LIBRARY_PATH variable for compilers to find libraries when in an environment, for example:
guix shell --pure gcc-toolchain clang --search-paths

This variable is used by GCC when linking libraries, e.g. when passing -lclang without the need to pass the path to the library in the arguments.
