This is because you didn't have the library available.

I highly recommend using the raylib-d:install script as mentioned 
in the 
[README](https://github.com/schveiguy/raylib-d?tab=readme-ov-file#method-1-install-appropriate-raylib-library-with-helper-tool)

Not only does this copy the *exactly correct* library to your 
local directory, it also offers to update your dub.json to 
provide the appropriate linker directives for linking.
