# Couple notes:
# -fontconfig is needed otherwise Qt Widgets render only boxes.
# -qt-doubleconversion avoids a dependency on libdouble-conversion.
# ICU avoids pulling in a bunch of large libraries, and hopefully we can get away without it.
# OpenGL is needed to render window decorations in Wayland, apparently.
