# Dependencies can be found in Source/cmake/OptionsGTK.cmake.
#
# * Missing WebRTC support, but ENABLE_WEB_RTC is experimental upstream.
# * media-libs/mesa dep is for libgbm
# * >=gst-plugins-opus-1.14.4-r1 for opusparse (required by MSE)
# * TODO: gst-plugins-base[X] is only needed when build configuration ends up
#         with GLX set, but that's a bit automagic too to fix
# * Softblocking <webkit-gtk-2.38:4 and <webkit-gtk-2.44:4.1 as since
# * 2.44 this SLOT ships the WebKitWebDriver binary; WebKitWebDriver is
#   an automation tool for web developers, which lets one control the
#   browser via WebDriver API - only one SLOT can ship it.
# * TODO: There is build-time conditional depend on gtk-4.13.4 for using
#   more efficient DmaBuf buffer type instead of EglImage, and
#   gtk-4.13.7 for a11y support - ensure it at some point with a min dep
# * at-spi2-core (atspi-2.pc) is checked at build time, but not linked
#   to in the gtk4 SLOT - is it an upstream check bug and only gtk-4.14
#   a11y support is used?
