qt-build-system wraps variables such as QT_PLUGIN_PATH with '=
instead of prefix, so when qtwayland is installed in a profile or
included in the environment, the application fails to see it.
Programs run with export QT_QPA_PLATFORM=wayland-egl will fail to
launch.
We could:
- Use 'prefix so that the parent environment's variables are
appended and users have to manually install qtwayland them
selves.
- Include qtwayland as an input to every qt package somehow. Can
the build system do that? Considering that Wayland seems to be
the future, I feel that Qt GUI applications should support it by
default. I mean, wayland is in the closure of qtbase anyway.
- Both? Why is '= used anyway?
How should this be done?
