8711bd0094Remove ENABLE_PIPEWIRE flag as it is ON by default
7ed1f11735Make pipewire and libxcomposite dependencies not optional
I tested removing pipewire and it makes screen capture impossible and clicking on previously created screen capture sources makes obs crash.
It also is a fundamental component of obs, and thus I see no use case without it.
I couldn't test removing libxcomposite but at this point I'm trusting the official obs-studio package.
