## Installation of Phonon

Install Phonon by running the following commands:

    mkdir build &&
    cd    build &&

    cmake -D CMAKE_INSTALL_PREFIX=/usr \
          -D CMAKE_BUILD_TYPE=Release  \
          -D PHONON_BUILD_QT5=OFF      \
          -W no-dev .. &&
    make

Now, as the `root` user:

    make install

## Command Explanations

`-D CMAKE_BUILD_TYPE=Release`: This switch is used to apply higher level of the compiler optimizations.

`-D PHONON_BUILD_QT5=OFF`: By default both the Qt5 and Qt6 versions of this package are built. We currently just want the Qt6 version, since nothing in BLFS uses the Qt5 version.
