Running OTClient with mesa3d

[VioletFlare]

Before creating an issue, please ensure:

• [x] This is a bug in the software that resides in this repository, and not a support matter (use https://otland.net/forums/otclient.494/ for support)
• [x] This issue is reproducible without changes to the code in this repository

Steps to reproduce (include any configuration/script required to reproduce)

1. Install a Windows environment without graphics drivers (i.e. a Hyper-V, Virtualbox or VMWare VM)
2. Download Mesa3D opengl32.dll and place it within the folder of otclient
3. Run otclient GL

Expected behaviour

I presume nobody ever tried this, since this is a very specific edge case, but I think, the mesa3d dll should be found. My rationale behind this, is to be able to test OTClient builds in an isolated environment.

Actual behaviour

The dll is not being found.

Environment

OS: Win11_24H2_English_x64 Running: OTClient 10.98.
