Installation of libplacebo

Install libplacebo by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      -Dtests=true        \
      -Ddemos=false       &&
ninja

To test the results, issue: ninja test. One test, opengl_surfaceless.c, is known to fail.

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Ddemos=false: This switch disables building the demo programs because building plplay is currently broken.

-Dtests=true: This switch enables building the code necessary to run the tests.
