Description

Hi,
Adding DYLD_FALLBACK_LIBRARY_PATH to the mac os X search path might be helpful.

As of High Sierra an onward, loading up the DYLD_LIBRARY_PATH variable HUGELY slows down all operations, since very file in the path is searched for every symbol on every process start, leading to long config and build times. By using the FALLBACK path, we avoid this while still being able to load the files.

We would like to understand more context. If you are referring to the utilities provided in cetlib, then you are permitted to specify an environment variable (upon construction of that object) which will be used to look for libraries to load. This facility is already provided.
