+********************************************************************************
+Using Proj.4 in CMake projects
+********************************************************************************
+
+The recommended way to use the Proj.4 library in a CMake project is to
+link to the imported library target ``${PROJ4_LIBRARIES}`` provided by
+the CMake configuration which comes with the library. Typical usage is:
+
+.. code::
+
+ find_package(PROJ4)
+
+ target_link_libraries(MyApp ${PROJ4_LIBRARIES})
+
+By adding the imported library target ``${PROJ4_LIBRARIES}`` to the
+target link libraries, CMake will also pass the include directories to
+the compiler. This requires that you use CMake version 2.8.11 or later.
+If you are using an older version of CMake, then add
+
+.. code::
+
+ include_directories(${PROJ4_INCLUDE_DIRS})
+
+The CMake command ``find_package`` will look for the configuration in a
+number of places. The lookup can be adjusted for all packages by setting
+the cache variable or environment variable ``CMAKE_PREFIX_PATH``. In
+particular, CMake will consult (and set) the cache variable
+``PROJ4_DIR``.
