|
--------------
|
|
|
|
|
|
|
|
|
|
Add sources to a target.
|
|
|
|
|
|
|
|
|
|
.. code-block:: cmake
|
|
|
|
|

target_sources(<target>
|
|
|
|
|
<INTERFACE|PUBLIC|PRIVATE> [items1...]
|
|
|
|
|
[<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])
|
|
|
|
|
|
|
|
|
|
Specifies sources to use when compiling a given target. Relative
|
|
|
|
|
source file paths are interpreted as being relative to the current
|
|
|
|
|
source directory (i.e. :variable:`CMAKE_CURRENT_SOURCE_DIR`). The
|
|
|
|
|
named ``<target>`` must have been created by a command such as
|
|
|
|
|
:command:`add_executable` or :command:`add_library` and must not be an
|
|
|
|
|
:ref:`ALIAS target <Alias Targets>`.
|
|
|
|
|
|
|
|
|
|
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>``.
|
|
|
|
|
(:ref:`IMPORTED targets <Imported Targets>` only support ``INTERFACE`` items.)
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
See also the :policy:`CMP0076` policy for older behavior related to the
|
|
|
|
|
handling of relative source file paths.
