SOURCES
|
|
-------
|
|
|
|
This specifies the list of paths to source files for the target.
|
|
The following commands all set or add to the ``SOURCES`` target property
|
|
and are the usual way to manipulate it:
|
|
|
|
* :command:`add_executable`
|
|
* :command:`add_library`
|
|
* :command:`add_custom_target`
|
|
* :command:`target_sources`
|
|
|
|
Contents of ``SOURCES`` may use
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
If a path starts with a generator expression, it is expected to
|
|
evaluate to an absolute path. Not doing so is considered undefined behavior.
|
|
|
|
Paths that are for files generated by the build will be treated
|
|
as relative to the build directory of the target, if the path is not
|
|
already specified as an absolute path. Note that whether a file is seen as
|
|
generated may be affected by policies :policy:`CMP0118` and :policy:`CMP0163`.
|
|
|
|
If a path does not start with a generator expression, is not an
|
|
absolute path and is not a generated file, it will be treated as relative to
|
|
the location selected by the first of the following that matches:
|
|
|
|
* If a file by the specified path exists relative to the target's source
|
|
directory, use that file.
|
|
* If policy :policy:`CMP0115` is not set to ``NEW``, try appending each
|
|
known source file extension to the path and check if that exists
|
|
relative to the target's source directory.
|
|
* Repeat the above two steps, this time relative to the target's binary
|
|
directory instead.
|
|
|
|
Note that the above decisions are made at generation time, not build time.

|
See the :manual:`cmake-buildsystem(7)` manual for more on defining
|
|
buildsystem properties.
