target_sources -------------- Add sources to a target. :: target_sources(<target> <INTERFACE|PUBLIC|PRIVATE> [items1...] [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...]) Specify sources to use when compiling a given target. The named ``<target>`` must have been created by a command such as :command:`add_executable` or :command:`add_library` and must not be an :prop_tgt:`IMPORTED Target`. The ``INTERFACE``, ``PUBLIC`` and ``PRIVATE`` keywords are required to specify the scope of the following arguments. ``PRIVATE`` and ``PUBLIC`` items will populate the :prop_tgt:`SOURCES` property of ``<target>``. ``PUBLIC`` and ``INTERFACE`` items will populate the :prop_tgt:`INTERFACE_SOURCES` property of ``<target>``. The following arguments specify sources. Repeated calls for the same ``<target>`` append items in the order called. Arguments to ``target_sources`` may use "generator expressions" with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` manual for available expressions. See the :manual:`cmake-buildsystem(7)` manual for more on defining buildsystem properties.
