"Failed to initialize OpenGL loader!" using Wayland (Fedora 42)

[nning]

Hi!

Since I'm using Wayland by default in Fedora 42, I get the following error when I try to start SonyHeadphonesClient:

$ ./SonyHeadphonesClient
[...]
Failed to initialize OpenGL loader!

ldd shows no missing libraries:

Thanks for your help and the work on this app!

When I output the error on glewInit like this,

GLenum err = glewInit();
if (err != GLEW_OK) {
    fprintf(stderr, "GLEW Error: %d %s\n", err, glewGetErrorString(err));
    return;
}

I get the following output:

GLEW Error: 4 Unknown error
