hook_library_info_build()
Add dynamic library definitions.
Modules may implement this hook to add dynamic library definitions. Static libraries, which do not depend on any runtime information, should be declared in a modulename.libraries.yml file instead.
Return value
array[] An array of library definitions to register, keyed by library ID. The library ID will be prefixed with the module name automatically.
