Meson build doesn't identify sys/capability.h ( libcap ) as a dependency

[duskmoss]

Is there an existing issue for this?

• [x] I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• [x] The issue occurs on upstream gamescope without any modifications

Current Behavior

meson setup build/ runs without issues ninja -C build/ fails because missing sys/capability.h

Easy to fix, installing dependency, but seems like meson should be checking if it exists?

Steps To Reproduce

Build according to instructions in README on a clean system/container
