Install libavif by running the following commands:
mkdir build &&
cd build &&
cmake -DCMAKE_INSTALL_PREFIX=/usr \

-DAVIF_CODEC_AOM=ON \
-DAVIF_BUILD_GDK_PIXBUF=ON \

This package does come with a test suite, but it requires gtest, which is not part of BLFS.
Now, as the root user:
ninja install
The AV1 format needs to be added to the loaders cache. As the
root user:
gdk-pixbuf-query-loaders --update-cache
-DAVIF_CODEC_AOM=ON: This
switch enables using the AOM codec. This package is useless without
at least one codec built in.
-DAVIF_BUILD_GDK_PIXBUF=ON:
This switch builds the AVIF loader for applications which use
gdk-pixbuf. Remove it if you have not installed gdk-pixbuf-2.42.10.
-DAVIF_CODEC_DAV1D=ON: Use this switch
if you have installed libdav1d and wish to
use it as a codec.
-DAVIF_CODEC_RAV1E=ON: Use this switch
if you have installed rav1e and wish to use it as a
codec.
-DAVIF_CODEC_SVT=ON: Use this switch if
you have installed svt-av1 and wish to
use it as a codec.
