Telegram/lib_webview depends on Qt component called WaylandCompositor. This component is a part of dev-qt/qtwayland package and since https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f2c0be9302270ad97d4b9a434adea3402fd6282b is controlled by the default-off USE flag, while net-im/telegram-desktop depends on plain dev-qt/qtwayland. This causes telegram-desktop to fail in the configure stage, because it is unable to find "required Qt component "WaylandCompositor"." The find_package clause in one of CMakeLists, which itself was added by the following commit: https://github.com/desktop-app/lib_webview/commit/6ee92c066c6b75349980670edf795990f26b2f62 and relaxed by https://github.com/desktop-app/lib_webview/commit/5b9092bcb27a207fed3cb2155bb98db46d7cedfa, requires WaylandCompositor if and only if Wayland integration is enabled (DESKTOP_APP_DISABLE_WAYLAND_INTEGRATION=no). This parameter is only available on Qt > 6 (see https://github.com/desktop-app/cmake_helpers/blob/b1b0e95b091f298c87cb9ec4458f426574221ca4/external/qt/package.cmake#L51), therefore only setups with both "qt6" and "wayland" USE flags turned on are affected. The easiest solution might be to depend on qtwayland[compositor(+)] like that: qt6? ( wayland? ( dbus? ( dev-qt/qtwayland:6[compositor(+)] ) !dbus? ( dev-qt/qtwayland:6 ) ) ) By the way, the commit which makes WaylandCompositor optional is included upstream since v4.9.4: https://github.com/telegramdesktop/tdesktop/commit/02e37ab2f202d51b8dbcf5cc554d0da2a82ae060
>By the way, the commit which makes WaylandCompositor optional >is included upstream since v4.9.4 I do assume webview is something scarcely used, if build system allows it then it should probably be optional and disabled by default in upcoming bump to match that it is disabled on qtwayland (thing is very large in qtwayland all while being scarcely used, essentially just a waste if feature is unused). (ideally please include emerge --info and a failed build.log for completeness even when it does not feel needed)
It's not only webview that requires qtwayland:6[compositor], it's also one of the requirements to get rid of client side decorations. The other is the correct value of DESKTOP_APP_DISABLE_WAYLAND_INTEGRATION, its evaluation by cmake is currently broken as mentioned in https://bugs.gentoo.org/910544

Sadly (AFAIK) there is no way to disable this particular component, so, most likely, we will have to make Telegram depend on dev-qt/qtwayland:6[compositor]

Back when I wrote this, the bump hadn't been done yet, but the bump did address this. qt6? ( wayland? ( >=dev-qt/qtwayland-6.5:6[compositor] ) webkit? ( >=dev-qt/qtdeclarative-6.5:6 >=dev-qt/qtwayland-6.5:6[compositor] Albeit I'm not sure the first one makes sense? I say that because it's preventing it to find compositor with USE=-webkit, but then still depends on it. -DCMAKE_DISABLE_FIND_PACKAGE_Qt${qt}WaylandClient=$(usex !wayland) ## Only used in Telegram/lib_webview/CMakeLists.txt -DCMAKE_DISABLE_FIND_PACKAGE_Qt${qt}WaylandCompositor=$(usex !webkit) On a side-note, Qt5 is going to make compositor optional soon'ish as well. https://github.com/gentoo/qt/pull/271
I was sure I added "wayland? ( >=dev-qt/qtwayland-6.5:6[compositor] )" for a reason, though I now can't remember what that was. I can't think of a reason it'd help anything, since it's disabled with FIND_PACKAGE, so I'm gonna remove it again.
