Recent updates to some packages make it impossible to build an Orca Master in Ubuntu-MATE 20.04

[Maksym Bilak]

The recent update of the libatk-bridge2.0-0 libatk-bridge2.0-dev and libatk-adapter packages makes it impossible to build Orca Master in Ubuntu-MATE 20.04. Reproduction steps:

1. You need to have Ubuntu-MATE 20.04 with the latest updates;

2. Install the following packages:

git autoconf autopoint yelp-tools libgstreamer1.0-dev python-gi-dev libatspi2.0-dev libatk-bridge2.0-dev

3. Clone the Orca repository:

git clone https://gitlab.gnome.org/GNOME/orca.git

4. Navigate to the cloned repository:

cd orca

5. Run the command:

./autogen.sh

The command output ends with the following lines:

checking for ATKBRIDGE... no
configure: error: Package requirements (atk-bridge-2.0 >= 2.26) were not met:
Package 'atk', required by 'atk-bridge-2.0', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables ATKBRIDGE_CFLAGS
and ATKBRIDGE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

If libatk-bridge2.0-0 libatk-bridge2.0-dev and libatk-adapter are forcibly downgraded to version 2.34.1-3, this error disappears.

Many thanks for fixing this issues.

Status changed to 'Confirmed' because the bug affects multiple users.

I guess this is due to the following change in at-spi2-atk:

* Meson: don't hard-code shared_library (!19).

which made meson emit a lot of new libraries in Requires.private of atk-bridge-2.0.pc, and thus the -dev package now has to add them in Depends.
