    <warning>
      <para>
        If a previous version of libportal is installed, move the
        headers out of the way so that later packages do not encounter
        conflicts (as the <systemitem role="username">root</systemitem>
        user):
      </para>
<screen role="root"><userinput>if [ -e /usr/include/libportal ]; then
    rm -rf /usr/include/libportal.old &amp;&amp;
    mv -vf /usr/include/libportal{,.old}
fi</userinput></screen>
    </warning>

    <para>
      If running the test suite, apply a patch to fix a dozen of test
      failures with python-dbusmock 0.30.0 or later:
    </para>

    <screen><userinput>patch -Np1 -i ../libportal-&libportal-version;-testsuite_fix-1.patch</userinput></screen>

    <para>
      Install <application>libportal</application> by running the following
      commands:
    </para>

<screen><userinput>mkdir build &amp;&amp;
cd    build &amp;&amp;

meson setup --prefix=/usr --buildtype=release -Ddocs=false .. &amp;&amp;
ninja</userinput></screen>

    <para>
      If you have <xref linkend='gi-docgen'/> installed and wish to build
      the API documentation for this package, issue:
    </para>

<screen role='nodump'><userinput>sed "/output/s/-1/-&libportal-version;/" -i ../doc/meson.build &amp;&amp;
meson configure -Ddocs=true                    &amp;&amp;
ninja</userinput></screen>

    <para>
      To test the results, issue: <command>ninja test</command>. Note that
      additional <filename>dbus-daemon</filename> processes may need to be
      killed after the tests are run.

    <para>
      <option>-Dbackends=gtk3,gtk4,qt5</option>: This switch allows you to set
      the available backends. You can use it to disable the dependency on gtk-3,
      gtk-4, or qt-5. Most applications that use libportal will use either
      gtk-4 or gtk-3. The default is to build all three backends.
