<p>Double colon in target name means <code class="docutils literal notranslate"><span class="pre">ALIAS</span></code> or <code class="docutils literal notranslate"><span class="pre">IMPORTED</span></code> target.</p>
<p>CMake 2.8.12 and lower allowed the use of targets and files with double
colons in <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>, with some buildsystem generators.</p>
<p>The use of double-colons is a common pattern used to namespace <code class="docutils literal notranslate"><span class="pre">IMPORTED</span></code>
targets and <code class="docutils literal notranslate"><span class="pre">ALIAS</span></code> targets. When computing the link dependencies of
a target, the name of each dependency could either be a target, or a file
on disk. Previously, if a target was not found with a matching name, the name
was considered to refer to a file on disk. This can lead to confusing error
messages if there is a typo in what should be a target name.</p>
<p>See also the <span class="target" id="index-0-prop_tgt:LINK_LIBRARIES_ONLY_TARGETS"></span><a class="reference internal" href="../prop_tgt/LINK_LIBRARIES_ONLY_TARGETS.html#prop_tgt:LINK_LIBRARIES_ONLY_TARGETS" title="LINK_LIBRARIES_ONLY_TARGETS"><code class="xref cmake cmake-prop_tgt docutils literal notranslate"><span class="pre">LINK_LIBRARIES_ONLY_TARGETS</span></code></a> target property.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior for this policy is to search for targets, then files on
disk, even if the search term contains double-colons. The <code class="docutils literal notranslate"><span class="pre">NEW</span></code> behavior
for this policy is to issue a <code class="docutils literal notranslate"><span class="pre">FATAL_ERROR</span></code> if a link dependency contains
double-colons but is not an <code class="docutils literal notranslate"><span class="pre">IMPORTED</span></code> target or an <code class="docutils literal notranslate"><span class="pre">ALIAS</span></code> target.</p>
<p>This policy was introduced in CMake version 3.0. CMake version
3.26.5 warns when the policy is not set and uses <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior. Use
the <span class="target" id="index-0-command:cmake_policy"></span><a class="reference internal" href="../command/cmake_policy.html#command:cmake_policy" title="cmake_policy"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">cmake_policy()</span></code></a> command to set it to <code class="docutils literal notranslate"><span class="pre">OLD</span></code> or <code class="docutils literal notranslate"><span class="pre">NEW</span></code> explicitly.</p>
