 2.1.2 In order to generates complete debug information to be used by GDB add
 -D_DEBUG=1 as a CMake Command-Line option.
 
+2.1.3 By default, installation prefix is "/usr/local". It can be changed using
+-D_INSTALL_PREFIX= as a CMake Command-Line option.

 Example:
-    cmake -D_DOXYGEN_DOC=1 -D_DEBUG=1 ../
+    cmake -D_DOXYGEN_DOC=1 -D_DEBUG=1 -D_INSTALL_PREFIX=/usr ../
 
 2.2.1 Use "make clean" if you want to delete all already compiled objects.
