ENABLE_HEADLESS=ON causes wx/bitmap.h: No such file or directory

When pulling latest of and building the application on Ubuntu 22.04 using the cmake .. -DENABLE_HEADLESS=ON flag an error is hit when building:

In file included from /home/kyle/Storage/Projects/MeleeSetup/tmp/Ishiiruka/Source/Core/Core/HW/EXI_DeviceSlippi.cpp:41:
/home/kyle/Storage/Projects/MeleeSetup/tmp/Ishiiruka/Source/Core/DolphinWX/Frame.h:11:10: fatal error: wx/bitmap.h: No such file or directory
   11 | #include <wx/bitmap.h>

Expected Behavior

The build should pass and generate a headless dolphin executable.

Current Behavior

The error above is raised. This is because wxWidgets_LIBRARIES has been disabled with the -DENABLE_HEADLESS=ON flag set and DolphinWX/CMakeLists.txt doesn't have any headers to work with.

Steps to Reproduce

1. git clone --recursive https://github.com/project-slippi/Ishiiruka.git
2. mkdir build
3. cmake .. -DENABLE_HEADLESS=ON && make -j1
4. PROFIT

Environment

• Ubuntu 22.04
• Rustc & cargo installed and sourced to current shell.

Getting the exact same thing on Ubuntu 20.04:

Try my other repository for Docker slippi that uses Vladfi's slippi to run in headless:
https://github.com/IAmAbszol/docker-slippi/tree/develop

There's also a regular slippi instance it can create for non-headless to evaluate and potentially even just play melee.

This is fixed on my exi-ai-rebase branch.
