+ <h4>Library conflicts</h4>
+ <p>Caveat: if you have a set of standard libraries in the default
+ location, say <code>/usr/lib</code> and a set of
+ private versions of the same libraries, for instance because you
+ need different revisions sometimes, in your own library directory,
+ you may receive an error message of the form:</p>
+
+<pre>
+CMake Warning at source/CMakeLists.txt:65 (ADD_LIBRARY):
+ Cannot generate a safe runtime search path for target deal_II.g because
+ files in some directories may conflict with libraries in implicit
+ directories:
+
+ runtime library [libtbb.so.2] in /usr/lib may be hidden by files in:
+ /my/private/lib
+
+ Some of these libraries may not be found correctly.
+</pre>
+
+<p>This is not a problem of CMake or deal.II, but rather a general
+ Linux problem. In order to fix this, you have two options:</p>
+<ol>
+<li>Choose all libraries either from your private directory or from
+ the standard one.</li>
+<li>Install all your private library versions in different directories.</li>
+</ol>
