+<h3>Use only native CMake commands</h3>
+
+<p>
+In order to have the ultimate flexibility, it is also possible to configure a
+user project using only native CMake commands, that is avoid usage of
+<code>DEAL_II_INITIALIZE_CACHED_VARIABLES</code> and <code>DEAL_II_SETUP_TARGET</code> macros.
+This can be achieved, for example, by the following code
+<pre class="cmake">
+CMAKE_MINIMUM_REQUIRED(VERSION 3.0.0)
+# Find and include deal.IIConfig.cmake
+FIND_PACKAGE(deal.II 8.5.0 REQUIRED
+  HINTS ${deal.II_DIR} ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR}
+  )
+PROJECT(example)
+
+# Include deal.IITargets.cmake
+INCLUDE(${DEAL_II_TARGET_CONFIG})
+
+ADD_EXECUTABLE(example example.src)
+TARGET_LINK_LIBRARIES(example ${DEAL_II_TARGET})
+</pre>
+</p>
