xwayland: check executable exists on init Instead of walking PATH like a previous proposal [1], this one checks that the Xwayland path specified in the pkg-config file exists. I think this is a reasonable compromise: - Users that don't have Xwayland installed system-wide won't get a bogus DISPLAY env variable set up. - Users that have WLR_XWAYLAND set won't be affected by this check. - Users that have Xwayland installed system-wide and a different Xwayland in their PATH still get their custom Xwayland. - Users that don't have Xwayland installed system-wide but have it somewhere else in PATH are left out. But this is pretty niche, and they can just set WLR_XWAYLAND. [1]: https://github.com/swaywm/wlroots/pull/2314 2021-02-04 17:56:28 +01:00			`if xwayland.found()`
