Subject: bug#43446: Qt Apps cant make use of qtwayland due to QT_PLUGIN_PATH '= wrapping
Date: Wed, 16 Sep 2020 21:16:50 +1000

[Message part 1 (text/plain, inline)]
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:

1. Use 'prefix so that the parent environment's variables are appended
   and users have to manually install qtwayland them selves.
2. 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.
3. Both? Why is '= used anyway?

How should this be done?
