# Sanitizers in Clang are supported by a specific runtime and Clang
# automatically links against the right runtime. When building statically
# linked binaries, the resulting binary will contain the runtime. Dynamically
# linked binaries will link against the dynamic version of the library.
#
# xctest bundles are necessarily dynamically linked, but linked in such a way
# that the sanitizer runtime is assumed to be on the @rpath. This finds the
# clang runtimes so that they can be supplied as needed.
