"Unable to load dynamic library ‘apcu.so’" error on PHP 8/nightly

I’m having an issue loading the apcu 5.1.19 extension on PHPH 8…0.0 on Win/IIS. All my other extensions load, but I get:

PHP Startup: Unable to load dynamic library ‘apcu’ (tried: J:\php\v8.0.0\ext\apcu (The specified module could not be found), J:\php\v8.0.0\ext\php_apcu.dll (The specified module could not be found)) in Unknown on line 0

Even though J:\php\v8.0.0\ext\php_apcu.dll exists.

We don’t support PHP on Windows, so you’ll have to ask your question elsewhere.
