target_sources
|
|
--------------
|
|
|
|
.. versionadded:: 3.1
|
|
|
|
Add sources to a target.
|
|
|
|
.. code-block:: cmake
|
|
|
|
target_sources(<target>
|
|
<INTERFACE|PUBLIC|PRIVATE> [items1...]
|
|
[<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
|
|
:command:`add_executable` or :command:`add_library` or
|
|
:command:`add_custom_target` and must not be an
|
|
:ref:`ALIAS target <Alias Targets>`. The ``<items>`` may use
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
.. versionadded:: 3.20
|
|
``<target>`` can be a custom target.
|
|
|
|
The ``INTERFACE``, ``PUBLIC`` and ``PRIVATE`` keywords are required to
|
|
specify the :ref:`scope <Target Usage Requirements>` of the source file paths
|
|
(``<items>``) that follow them. ``PRIVATE`` and ``PUBLIC`` items will
|
|
populate the :prop_tgt:`SOURCES` property of ``<target>``, which are used when
|
|
building the target itself. ``PUBLIC`` and ``INTERFACE`` items will populate the
|
|
:prop_tgt:`INTERFACE_SOURCES` property of ``<target>``, which are used
|
|
when building dependents. A target created by :command:`add_custom_target`
|
|
can only have ``PRIVATE`` scope.
|
|
|
|
Repeated calls for the same ``<target>`` append items in the order called.
|
|
|
|
.. versionadded:: 3.3
|
|
Allow exporting targets with :prop_tgt:`INTERFACE_SOURCES`.
|
|
|
|
.. versionadded:: 3.11
|
|
Allow setting ``INTERFACE`` items on
|
|
:ref:`IMPORTED targets <Imported Targets>`.
|
|
|
|
.. versionchanged:: 3.13
|
|
Relative source file paths are interpreted as being relative to the current
|
|
source directory (i.e. :variable:`CMAKE_CURRENT_SOURCE_DIR`).
|
|
See policy :policy:`CMP0076`.
|
|
|
|
A path that begins with a generator expression is left unmodified.
|
|
When a target's :prop_tgt:`SOURCE_DIR` property differs from
|
|
:variable:`CMAKE_CURRENT_SOURCE_DIR`, use absolute paths in generator
|
|
expressions to ensure the sources are correctly assigned to the target.
|
|
|
|
.. code-block:: cmake
|
|
|
|
# WRONG: starts with generator expression, but relative path used
|
|
target_sources(MyTarget PRIVATE "$<$<CONFIG:Debug>:dbgsrc.cpp>")
|
|
|
|
# CORRECT: absolute path used inside the generator expression
|
|
target_sources(MyTarget PRIVATE "$<$<CONFIG:Debug>:${CMAKE_CURRENT_SOURCE_DIR}/dbgsrc.cpp>")
|
|
|
|
See the :manual:`cmake-buildsystem(7)` manual for more on defining
|
|
buildsystem properties.

File Sets
|
|
^^^^^^^^^
|
|
|
|
.. versionadded:: 3.23
|
|
|
|
.. code-block:: cmake
|
|
|
|
target_sources(<target>
|
|
[<INTERFACE|PUBLIC|PRIVATE>
|
|
[FILE_SET <set> [TYPE <type>] [BASE_DIRS <dirs>...] [FILES <files>...]]...
|
|
]...)
|
|
|
|
Adds a file set to a target, or adds files to an existing file set. Targets
|
|
have zero or more named file sets. Each file set has a name, a type, a scope of
|
|
``INTERFACE``, ``PUBLIC``, or ``PRIVATE``, one or more base directories, and
|
|
files within those directories. The acceptable types include:
|
|
|
|
``HEADERS``
|
|
|
|
Sources intended to be used via a language's ``#include`` mechanism.
|
|
|
|
``CXX_MODULES``
|
|
|
|
.. note ::
|
|
|
|
Experimental. Gated by ``CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API``
|
|
|
|
Sources which contain C++ interface module or partition units (i.e., those
|
|
using the ``export`` keyword). This file set type may not have an
|
|
``INTERFACE`` scope except on ``IMPORTED`` targets.
|
|
|
|
The optional default file sets are named after their type. The target may not
|
|
be a custom target or :prop_tgt:`FRAMEWORK` target.
|
|
|
|
Files in a ``PRIVATE`` or ``PUBLIC`` file set are marked as source files for
|
|
the purposes of IDE integration. Additionally, files in ``HEADERS`` file sets
|
|
have their :prop_sf:`HEADER_FILE_ONLY` property set to ``TRUE``. Files in an
|
|
``INTERFACE`` or ``PUBLIC`` file set can be installed with the
|
|
:command:`install(TARGETS)` command, and exported with the
|
|
:command:`install(EXPORT)` and :command:`export` commands.
|
|
|
|
Each ``target_sources(FILE_SET)`` entry starts with ``INTERFACE``, ``PUBLIC``, or
|
|
``PRIVATE`` and accepts the following arguments:
|
|
|
|
``FILE_SET <set>``
|
|
|
|
The name of the file set to create or add to. It must contain only letters,
|
|
numbers and underscores. Names starting with a capital letter are reserved
|
|
for built-in file sets predefined by CMake. The only predefined set names
|
|
are those matching the acceptable types. All other set names must not start
|
|
with a capital letter or
|
|
underscore.
|
|
|
|
``TYPE <type>``
|
|
|
|
Every file set is associated with a particular type of file. Only types
|
|
specified above may be used and it is an error to specify anything else. As
|
|
a special case, if the name of the file set is one of the types, the type
|
|
does not need to be specified and the ``TYPE <type>`` arguments can be
|
|
omitted. For all other file set names, ``TYPE`` is required.
|
|
|
|
``BASE_DIRS <dirs>...``
|
|
|
|
An optional list of base directories of the file set. Any relative path
|
|
is treated as relative to the current source directory
|
|
(i.e. :variable:`CMAKE_CURRENT_SOURCE_DIR`). If no ``BASE_DIRS`` are
|
|
specified when the file set is first created, the value of
|
|
:variable:`CMAKE_CURRENT_SOURCE_DIR` is added. This argument supports
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
No two base directories for a file set may be sub-directories of each other.
|
|
This requirement must be met across all base directories added to a file set,
|
|
not just those within a single call to ``target_sources()``.
|
|
|
|
``FILES <files>...``
|
|
|
|
An optional list of files to add to the file set. Each file must be in
|
|
one of the base directories, or a subdirectory of one of the base
|
|
directories. This argument supports
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
If relative paths are specified, they are considered relative to
|
|
:variable:`CMAKE_CURRENT_SOURCE_DIR` at the time ``target_sources()`` is
|
|
called. An exception to this is a path starting with ``$<``. Such paths
|
|
are treated as relative to the target's source directory after evaluation
|
|
of generator expressions.
|
|
|
|
The following target properties are set by ``target_sources(FILE_SET)``,
|
|
but they should not generally be manipulated directly:
|
|
|
|
For file sets of type ``HEADERS``:
|
|
|
|
* :prop_tgt:`HEADER_SETS`
|
|
* :prop_tgt:`INTERFACE_HEADER_SETS`
|
|
* :prop_tgt:`HEADER_SET`
|
|
* :prop_tgt:`HEADER_SET_<NAME>`
|
|
* :prop_tgt:`HEADER_DIRS`
|
|
* :prop_tgt:`HEADER_DIRS_<NAME>`
|
|
|
|
For file sets of type ``CXX_MODULES``:
|
|
|
|
* :prop_tgt:`CXX_MODULE_SETS`
|
|
* :prop_tgt:`INTERFACE_CXX_MODULE_SETS`
|
|
* :prop_tgt:`CXX_MODULE_SET`
|
|
* :prop_tgt:`CXX_MODULE_SET_<NAME>`
|
|
* :prop_tgt:`CXX_MODULE_DIRS`
|
|
* :prop_tgt:`CXX_MODULE_DIRS_<NAME>`
|
|
|
|
Target properties related to include directories are also modified by
|
|
``target_sources(FILE_SET)`` as follows:
|
|
|
|
:prop_tgt:`INCLUDE_DIRECTORIES`
|
|
|
|
If the ``TYPE`` is ``HEADERS``, and the scope of the file set is ``PRIVATE``
|
|
or ``PUBLIC``, all of the ``BASE_DIRS`` of the file set are wrapped in
|
|
:genex:`$<BUILD_INTERFACE>` and appended to this property.
|
|
|
|
:prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`
|
|
|
|
If the ``TYPE`` is ``HEADERS``, and the scope of the file set is
|
|
``INTERFACE`` or ``PUBLIC``, all of the ``BASE_DIRS`` of the file set are
|
|
wrapped in :genex:`$<BUILD_INTERFACE>` and appended to this property.
