Unable to build QT in Linux due to missing 'discord_rcp.h' even with -DENABLE_DISCORD_RPC=OFF

[paljardine]

OS: Fedora Linux 40 (KDE Plasma) x86_64
Kernel: 6.11.4-201.fc40.x86_64

It seems like discord_rpc_handler.h is unable to find 'discord_rpc.h'. Adding ifdefs for ENABLE_DISCORD_RPC to the following files allows the build to proceed:

discord_rpc_handler.h

emulator.cpp

main_window.cpp

settings_dialog.cpp

There should be a way to get discord_rpc_handler to properly include discord_rpc.h, but this works as quick hack.

I confirm, I have the same issue.
I am building on "Debian Testing" with kernel 6.11 and I am using clang19. I also used -DENABLE_DISCORD_RPC=OFF.

When adding -DENABLE_QT_GUI=OFF I can successfully build the project.
