Add a `CMAKE_Swift_COMPILATION_MODE` variable and corresponding `Swift_COMPILATION_MODE` target property to control the compilation mode. Select among `wholemodule`, `singlefile`, and `incremental`. Add policy CMP0157 to remove the default `-wmo` flags in favor of the abstract setting. Issue: #25366

Swift_COMPILATION_MODE
|
|
----------------------
|
|
|
|
.. versionadded:: 3.29
|
|
|
|
Specify how Swift compiles a target.
|
|
|
|
The allowed values are:
|
|
|
|
.. include:: Swift_COMPILATION_MODE-VALUES.txt
|
|
|
|
Use :manual:`generator expressions <cmake-generator-expressions(7)>` to support
|
|
per-configuration specification. For example, the code:
|
|
|
|
.. code-block:: cmake
|
|
|
|
add_library(foo foo.swift)
|
|
set_property(TARGET foo PROPERTY
|
|
Swift_COMPILATION_MODE "$<IF:$<CONFIG:Release>,wholemodule,incremental>")
|
|
|
|
sets the Swift compilation mode to wholemodule mode in the release configuration
|
|
and sets the property to incremental mode in other configurations.
|
|
|
|
The property is initialized from the value of the
|
|
:variable:`CMAKE_Swift_COMPILATION_MODE` variable, if it is set. If the property
|
|
is not set or is empty, then CMake uses the default value ``incremental`` to
|
|
specify the swift compilation mode.
|
|
|
|
.. note::
|
|
|
|
This property only has effect when policy :policy:`CMP0157` is set to ``NEW``
|
|
prior to the first :command:`project` or :command:`enable_language` command
|
|
that enables the Swift language.
