    <title>Installation of qt5 components</title>

    <para>
      There are a few extra components needed for different packages in BLFS.
      These are 
      <emphasis role="bold">qtimageformats</emphasis>, 
      <emphasis role="bold">qtlocation</emphasis>, 
      <emphasis role="bold">qtwebchannel</emphasis>, 
      <emphasis role="bold">qtdoc</emphasis>, and
      <emphasis role="bold">qtmultimedia</emphasis>. 
      Only those components specified for a specific 
      package are needed. You only need to build the relevant component(s). 
    </para>

    <para>
      First, apply a patch to pull in the fixes curated by KDE for some of the
      modules listed above:
    </para>

<screen><userinput remap="pre">patch -Np1 -i ../qt-everywhere-opensource-src-5.15.10-kf5-1.patch</userinput></screen>

    <para>
      Install each desired component by running the following commands:
    </para>

<screen><userinput>cd &lt;component&gt;
qmake &lt;component&gt;.pro
make</userinput></screen>

    <para>
      As the &root; user:

<screen role="root"><userinput>make install</userinput></screen>

    <!-- EDITORS NOTE: This package uses INSTALL_ROOT= instead of DESTDIR= for
         installing in a temporary directory. -->

    <para>
      Remove references to the build directory from installed library
      dependency (prl) files by running the following
      command as the &root; user:
    </para>

<screen role="root"><userinput>find $QT5DIR/ -name \*.prl \
