target_compile_options
|
|
----------------------
|
|
|
|
Add compile options to a target.
|
|
|
|
.. code-block:: cmake
|
|
|
|
target_compile_options(<target> [BEFORE]
|
|
<INTERFACE|PUBLIC|PRIVATE> [items1...]
|
|
[<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])
|
|
|
|
Adds options to the :prop_tgt:`COMPILE_OPTIONS` or
|
|
:prop_tgt:`INTERFACE_COMPILE_OPTIONS` target properties. These options
|
|
are used when compiling the given ``<target>``, which 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>`.
|
|
|
|
Arguments
|
|
^^^^^^^^^
|
|
|
|
If ``BEFORE`` is specified, the content will be prepended to the property
|
|
instead of being appended.
|
|
|
|
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:`COMPILE_OPTIONS` property of
|
|
``<target>``. ``PUBLIC`` and ``INTERFACE`` items will populate the
|
|
:prop_tgt:`INTERFACE_COMPILE_OPTIONS` property of ``<target>``.
|
|
(:ref:`IMPORTED targets <Imported Targets>` only support ``INTERFACE`` items.)
|
|
The following arguments specify compile options. Repeated calls for the same
|
|
``<target>`` append items in the order called.
|
|
|
|
Arguments to ``target_compile_options`` 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.

^^^^^^^^

|
|
|
This command can be used to add any options. However, for adding
|
|
preprocessor definitions and include directories it is recommended
|
|
to use the more specific commands :command:`target_compile_definitions`
|
|
and :command:`target_include_directories`.
|
|
|
|
For directory-wide settings, there is the command :command:`add_compile_options`.
