| 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. | External libraries is configured through the files at '''dune/cmake/Libraries'''.

| 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'''. | To reduce compile time and binary size, an option is to only build a selection of the tasks included with DUNE.
