-When tracking a fast changing software like FlightGear/Git it is highly advisable to install it in a separate directory. That way one can also easily build and reinstall without being root, which greatly reduces the risk of messing up one's system.
+Flightgear, Simgear, and OpenSceneGraph now use <tt>cmake</tt>. See the [http://www.cmake.org/Wiki/CMake_Useful_Variables CMake wiki] for additional documentation.
-To install in a directory of your choice, add the <code>CMAKE_INSTALL_PREFIX</code> argument to <code>cmake</code>. E.g., <code>-DCMAKE_INSTALL_PREFIX==/path/to/your/fgInstallation</code>. I would recommend installing all of OSG, plib, SimGear and FlightGear with the same prefix.
+CMake allows users to create "out-of-source" builds, which means build files are created in a separate directory, and many variants can be maintained. To use out-of-source builds, simply create a new directory and pass the path to source to <code>cmake</code>.
+=== Example "out-of-source" build with CMake ===
+<syntaxhighlight lang="bash">
+simgear $ mkdir ../build.simgear
+simgear $ cd ../build.simgear
+build.simgear $ cmake ../simgear
+</syntaxhighlight>
+After CMake has run, you can <code>make && make install</code>.
