Brotli provides a general-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling. Its libraries are particularly used for WOFF2 fonts on webpages.

Install brotli by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-G Ninja .. &&
ninja
To test the results, issue: ninja test.
Now, as the root user:
ninja install
If desired, build the Python3 bindings:
cd .. &&
sed -e '/libraries +=/s/=.*/= [required_system_library[3:]]/' \
-e '/package_configuration/d' \
-e '/pkgconfig/d' \
-i setup.py &&
USE_SYSTEM_BROTLI=1 \
pip3 wheel -w dist --no-build-isolation --no-deps --no-cache-dir $PWD
Install the Python3 bindings as
the root user:
pip3 install --no-index --find-links dist --no-user Brotli
To test the Python3 binding, issue: pytest.
sed ... -i setup.py:
Allow building the Python3 binding
with USE_SYSTEM_BROTLI=1 but without the
Python 3 pkgconfig module (that BLFS does not provide) installed.
USE_SYSTEM_BROTLI=1: Stop setup.py from rebuilding the entire package all
over again, use the already installed libraries for the
Python3 binding instead.
