Cannot `load-library` with binary Windows release

[swapneils]

I tried loading libraries via code in init.lisp on the Windows 2.1.0 binary (released July), but get an error that the libraries couldn't be found.

When trying to use M-x load-library, I get the following:

Component "lem-contrib" not found
Backtrace for: #<SB-THREAD:THREAD "editor" RUNNING {1003CB0553}>
...
7: (ERROR ASDF/FIND-COMPONENT:MISSING-COMPONENT :REQUIRES "lem-contrib")

...

Since it isn't on Quicklisp and the release zip doesn't have any free-floating Lisp files, how would we make lem-contrib visible to Lem (without just using git-clone to get a copy of the lem repository and hoping there aren't any breaking changes to contrib since the last release)? I don't see any documentation or previous issues regarding this error.

Since the libraries are not in the Lem default image, It's not possible to load them without them been in the quicklisp path:

(define-command load-library (name)
    ((prompt-for-library "load library: " :history-symbol 'load-library))
  "Load the Lisp library named NAME."
  (message "Loading ~A." name)
  (cond ((ignore-errors (maybe-quickload (format nil "lem-~A" name) :silent t))
         (message "Loaded ~A." name))
        (t (message "Can't find Library ~A." name))))

As I point out (https://github.com/lem-project/lem/issues/1032#issuecomment-1703902771), the contrib directory is just a temporal solution until we migrate the packages to Ultralistp
