dynamic-library-alist is a variable defined in emacs.c.
Value
nil
Documentation
Alist of dynamic libraries vs external files implementing them.
Each element is a list (LIBRARY FILE...), where the car is a symbol representing a supported external library, and the rest are strings giving alternate filenames for that library.
Emacs tries to load the library from the files in the order they appear on the list; if none is loaded, the running session of Emacs won't have access to that library.
Note that image types pbm and xbm do not need entries in this variable
because they do not depend on external libraries and are always available.
Also note that this is not a generic facility for accessing external libraries; only those already known by Emacs will be loaded.
Probably introduced at or before Emacs version 24.1.
