New in version 3.1.

Add sources to a target.

  [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

Specifies sources to use when building a target and/or its dependents. The named <target> must have been created by a command such as add_executable() or add_library() or add_custom_target() and must not be an ALIAS target.

Changed in version 3.13: Relative source file paths are interpreted as being relative to the current source directory (i.e. CMAKE_CURRENT_SOURCE_DIR). See policy CMP0076.

New in version 3.20: <target> can be a custom target.

The INTERFACE, PUBLIC and PRIVATE keywords are required to specify the scope of the items following them. PRIVATE and PUBLIC items will populate the SOURCES property of <target>, which are used when building the target itself. PUBLIC and INTERFACE items will populate the INTERFACE_SOURCES property of <target>, which are used when building dependents. The following arguments specify sources. Repeated calls for the same <target> append items in the order called. The targets created by add_custom_target() can only have PRIVATE scope.

New in version 3.3: Allow exporting targets with INTERFACE_SOURCES.

New in version 3.11: Allow setting INTERFACE items on IMPORTED targets.

Arguments to target_sources may use "generator expressions" with the syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions. See the cmake-buildsystem(7) manual for more on defining buildsystem properties.
