Comment (by kencu):

 According to <https://gitlab.kitware.com/cmake/community/wikis/doc/cmake
 /RPATH-handling> the linker will search for dependencies in the following
 order:

 1. DYLD_LIBRARY_PATH - an environment variable which holds a list of
 directories
 1. RPATH - a list of directories which is linked into the executable.
 These can contain @loader_path and @executable_path.
 1. builtin directories - /lib /usr/lib
 1. DYLD_FALLBACK_LIBRARY_PATH - an environment variable which holds a list
 of directories
