 ===== Adding External Libraries =====
+External libraries is configured through the files at '''dune/cmake/Libraries'''. These check if the respective library is available, and then adds the needed include directories with headers and linked libraries. In addition, they each set cmake flags like '''DUNE_USING_JPEG''' or '''DUNE_SYS_HAS_JPEG'''. These flags can then be used cmakefiles of individual tasks to ensure the task is only built if the required library was successfully included.
+===== Building with only a Subset of Tasks =====
+To reduce compile time and binary size, an option is to only build a selection of the tasks included with DUNE. This can be done by setting the ''TASK_FILE'' variable when invoking cmake, and pointing it towards a file containing calls to either ''dune_add_task'' or ''dune_add_tasks''. Example call:
+  cmake -DTASK_FILE=../dune/user/taskFile.cmake ../dune
+Example of content to put in the ''TASK_FILE'':
+  dune_add_tasks(${PROJECT_SOURCE_DIR}/user/src)
+  dune_add_task(${PROJECT_SOURCE_DIR}/src Transports/Announce/Task.cmake)
