<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Making wayland mandatory in libkscreen (and also in other modules, like plasma-integration, kwin, kscreenlocker) means killing outright any attempt to make Plasma build on non-Linux platforms. Please reconsider this, thanks.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Can you please point me to the discussion you had with distro packagers?</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So let's go from "theoretically not possible" to "practically not possible". Where is it not possible to have a Wayland dependency?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Concerning the discussion: a quick search showed me https://mail.kde.org/pipermail/kde-distro-packagers/2015-July/000076.html, but there must be an older one already as we use it in plasma-workspace (kscreenlocker) since Plasma 5.2 IIRC. This makes it difficult for me to point you to the discussion as it's really a long time ago.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The only party involved there is a Slackware packager, which is a Linux distro (where the Wayland libraries can be built fine). I don't see anyone mentioning non-Linux support.</p>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">That's the second attempt at this I see (the first one was beginning of 2013 IIRC), yet none of this code as been upstreamed yet.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Well I find it strange that I got code from BSD users for new KWin. If it were impossible to build KWin anymore that wouldn't work ;-)</p></pre>
