Installation of gegl

If installing over a previous version of gegl, one module needs to be removed. As the root user, run:

rm -f /usr/lib/gegl-0.4/vector-fill.so

Install gegl by running the following commands:

mkdir build &&
cd    build &&

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

To run the tests, issue: ninja test. 7 tests in the gegl:ff-load-save portion of the test suite are known to fail due to incompatibilities with ffmpeg-6.0.

Now, as the root user:

ninja install
