 To build from source you also need:
 
+- Meson and Ninja
 - A C++ compiler
 - headers for libpng and libjpeg
 - Python headers
 - glib-compile-resources and optionally xmllint
 - pkg-config
-- Python setuptools package
 
 On Debian/Ubuntu, these can be installed with:
 
-    sudo apt install build-essential libglib2.0-dev-bin libjpeg-dev libpng-dev libpython3-dev libxml2-utils pkg-config python3-setuptools

 If FFmpeg is installed it will be possible to create videos.
 
 On macOS, you can install the dependencies using brew:
 
-    brew install librsvg python3 pkg-config gtk4 pygobject3 libpng jpeg
+    brew install librsvg meson python3 pkg-config gtk4 pygobject3 libpng jpeg
