Well, `bin/` and `libs/` are in the same directory.

I tried `bin/libs/` as well as you describe here. It did not work.

Actually, it is quite strange that it fails to load the 
[CSFML](https://www.sfml-dev.org/download/csfml/) library dlls in 
`libs/` (I download CSFML2.5) since that is what I do with 
[GLFW/OpenGL](https://github.com/rillki/d-glfw-opengl-project-template) example as well for Windows 10.

**Even this fails: `loadSFMLGraphics("libs/csfml-graphics.dll")`**

I have the following structure:
```
- bin/
- libs/
- source/
- dub.json
- dub.selections.json
```

My `dub.json`:
```Json
{
	"authors": [
		"rillki"
	],
	"copyright": "Copyright © 2023, rillki",
	"dependencies": {
		"bindbc-sfml": "~>1.0.2"
	},
	"description": "D/SFML project template",
	"license": "BSL",
	"name": "d-sfml-project-template",
	"targetPath": "bin",
	"versions": [
		"SFML_Audio",
		"SFML_Graphics",
		"SFML_Network",
		"SFML_System",
		"SFML_Window",
		"SFML_250"
	]
}
```

My `source/app.d`:
```d
module app;

import std.stdio: writeln;
import bindbc.sfml;

void main() {
     version(Windows) {
         import bindbc.loader;
         setCustomLoaderSearchPath("libs");
     }

     // attempt at loading sfml
     if(!loadSFML()) {
         writeln("Failed to load SFML library!");
         return;
     }

     // window dimensions
     enum width = 720;
     enum height = 480;
     enum title = "D/SFML project";

     // create window
     auto window = sfWindow_create(sfVideoMode(width, height), 
title.toStringz, sfWindowStyle.sfDefaultStyle, null);
     scope(exit) { sfWindow_destroy(window); }

     while(sfWindow_isOpen(window)) {
         // process events
         sfEvent event;
         while(sfWindow_pollEvent(window, &event)) {
             if(event.type == sfEventType.sfEvtClosed) {
                 sfWindow_close(window);
             }
         }

         // ...
     }
}

```

I will try to make it work... Meanwhile, if someones spots what I 
am doing wrong, please reply to this post.
