Unable to launch on Fedora 41

[Tripletth]

After updating from Fedora 40 to Fedora 41, Dolphin fails to launch from the Slippi launcher with the following errors:

I'm running Slippi from the Slippi-Launcher-2.11.6-x86_64.AppImage.

Further version info as displayed in the Slippi launcher:

Version 2.11.6 (4ab0676)
Build 20240413
Linux 6.11 (6.11.5-300-fc41.x86_64)

this has been discussed a bit in the discord, but i couldn't find a good cause based on the user reports apart, from it being a newer version issue

https://discord.com/channels/328261477372919811/1300268326651695146

currently, the best suggestion i can give is to compile the binary and place it in ~/.config/Slippi Launcher/netplay

I tried compiling with ./build-linux.sh, but got an error saying X11 is required:

-- Could NOT find X11 (missing: X11_X11_INCLUDE_PATH X11_X11_LIB) 
X11 support disabled
CMake Error at CMakeLists.txt:565 (message):
  

  No suitable display platform found

  Requires x11 to run


-- Configuring incomplete, errors occurred!

My graphics platform is Wayland (Fedora 41 KDE) instead of X11, maybe Wayland isn't supported? OS info:

Pretty sure it's only x11, until I make a PR into dolphin for wayland vulkan support
