how to get Orca build dep after backport update?

[Pavel Vlček <vlcekpavel93@gmail.com>]

Hi,

I updated all accessibility packages as Debian Accessibility wiki describes:

sudo apt-get install at-spi2-core/buster-backports 
gir1.2-atspi-2.0/buster-backports gir1.2-atk-1.0/buster-backports 
libatk-adaptor/buster-backports python3-pyatspi/buster-backports 
orca/buster-backports libatk-wrapper-java-jni/buster-backports 
brltty/buster-backports

how can I now use apt-get build-dep orca? It not works, because some 
version conflicts are here, I want to use Orca Master now.

Thanks,

Pavel
