+### Static Builds
-The `ext/` subdirectory contains a handful of basic scripts which each pull
-down a known-good copy of an AV1 codec and make a local static library build.
-Most scripts require CMake, Ninja and NASM. dav1d uses Meson instead of CMake,
-and rav1e uses cargo (Rust). Check each library's documentation for an exact
-list of requirements.
+When set to `LOCAL`, these libraries and the other dependencies will be pulled
+locally by CMake to known-good versions.
-If you want to statically link any codec into your local (static) build of
-libavif, building using one of these scripts and then setting the associated
-`AVIF_CODEC_*` to `LOCAL` is a convenient method, but you must make sure to
-disable `BUILD_SHARED_LIBS` in CMake to instruct it to make a static libavif
-library.
-
-If you want to build/install shared libraries for AV1 codecs, you can still
-peek inside of each script to see where the current known-good SHA is for each
-codec.
+To override a local dependency version or to use a custom build of a dependency,
+first run the associated script in the `ext/` subdirectory.
