    # The soname / install name of libtbb and libtbbmalloc are versioned only
    # by the minor version (e.g., `libtbb.so.12`), but Open CASCADE's CMake
    # config files reference the fully-versioned filenames (e.g.,
    # `libtbb.so.12.11`).
    # This mandates rebuilding opencascade upon tbb's minor version updates.
    # To avoid this, we change the fully-versioned references to the minor-only
    # version. For example:
    #   libtbb.so.12.11 => libtbb.so.12
    #   libtbbmalloc.so.2.11 => libtbbmalloc.so.2
    #   libtbb.12.11.dylib => libtbb.12.dylib
    #   libtbbmalloc.2.11.dylib => libtbbmalloc.2.dylib
