This change udpates the ldcache locator to read the ldcache at construction and use these contents to perform future lookups against. Each of the cache entries are resolved and lookups return the resolved target. Assuming a symlink chain: libcuda.so -> libcuda.so.1 -> libcuda.so.VERSION, this means that libcuda.so.VERION will be returned for any of the following inputs: libcuda.so, libcuda.so.1, libcudal.so.*.
