Installation of At-Spi2 Core

Install At-Spi2 Core by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr --buildtype=release .. &&

The test suite also requires the glib schemas of the package to be installed already. To test the results, install the package first, then issue: dbus-run-session ninja test. One test, atk-test, is known to timeout on some systems.

Now, as the root user: 

ninja install
