<p>Additional public interface files on which a target binary depends for linking.</p>
<p>This property is supported only by <span class="target" id="index-0-generator:Ninja"></span><a class="reference internal" href="../generator/Ninja.html#generator:Ninja" title="Ninja"><code class="xref cmake cmake-generator docutils literal notranslate"><span class="pre">Ninja</span></code></a> and
<a class="reference internal" href="../manual/cmake-generators.7.html#makefile-generators"><span class="std std-ref">Makefile Generators</span></a>.
It is intended to specify dependencies on &quot;linker scripts&quot; for
custom Makefile link rules.</p>
<p>When target dependencies are specified using <span class="target" id="index-0-command:target_link_libraries"></span><a class="reference internal" href="../command/target_link_libraries.html#command:target_link_libraries" title="target_link_libraries"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">target_link_libraries()</span></code></a>,
CMake will read this property from all target dependencies to determine the
build properties of the consumer.</p>
<p>Contents of <code class="docutils literal notranslate"><span class="pre">INTERFACE_LINK_DEPENDS</span></code> may use &quot;generator expressions&quot;
with the syntax <code class="docutils literal notranslate"><span class="pre">$&lt;...&gt;</span></code>. See the <span class="target" id="index-0-manual:cmake-generator-expressions(7)"></span><a class="reference internal" href="../manual/cmake-generator-expressions.7.html#manual:cmake-generator-expressions(7)" title="cmake-generator-expressions(7)"><code class="xref cmake cmake-manual docutils literal notranslate"><span class="pre">cmake-generator-expressions(7)</span></code></a>

-manual for more on defining buildsystem properties.</p>
<p>Link dependency files usage requirements commonly differ between the build-tree
and the install-tree. The <code class="docutils literal notranslate"><span class="pre">BUILD_INTERFACE</span></code> and <code class="docutils literal notranslate"><span class="pre">INSTALL_INTERFACE</span></code>
generator expressions can be used to describe separate usage requirements
based on the usage location. Relative paths are allowed within the
<code class="docutils literal notranslate"><span class="pre">INSTALL_INTERFACE</span></code> expression and are interpreted relative to the
installation prefix. For example:</p>
<div class="highlight-cmake notranslate"><div class="highlight"><pre><span></span><span class="nf">set_property(</span><span class="no">TARGET</span><span class="w"> </span><span class="nb">mylib</span><span class="w"> </span><span class="no">PROPERTY</span><span class="w"> </span><span class="no">INTERFACE_LINK_DEPENDS</span><span class="w"></span>
