Installation of libaom

Install libaom by running the following commands:

mkdir aom-build &&
cd    aom-build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_BUILD_TYPE=Release  \
      -DBUILD_SHARED_LIBS=1       \
      -DENABLE_DOCS=no            \
      -G Ninja .. &&
ninja

To test the results, issue: ninja runtests. Note that the tests take an extremely long time to run.

Now, as the root user:

ninja install &&
rm -v /usr/lib/libaom.a

Command Explanations

-DBUILD_SHARED_LIBS=1: This switch builds shared versions of the libraries.

-DENABLE_DOCS=no: This switch disables building the documentation because it fails due to an incompatibility with the latest version of Doxygen-1.10.0.

-DENABLE_NASM=yes: Use this switch if you have both yasm-1.3.0 and NASM-2.16.01 installed and wish to use nasm instead of yasm.
