+CMAKE_MSVC_DEBUG_INFORMATION_FORMAT
+-----------------------------------
+
+.. versionadded:: 3.25
+
+Select the MSVC debug information format targeting the MSVC ABI.
+This variable is used to initialize the
+:prop_tgt:`MSVC_DEBUG_INFORMATION_FORMAT` property on all targets as they are
+created.  It is also propagated by calls to the :command:`try_compile` command
+into the test project.
+
+The allowed values are:
+
+.. include:: ../prop_tgt/MSVC_DEBUG_INFORMATION_FORMAT-VALUES.txt
+
+Use :manual:`generator expressions <cmake-generator-expressions(7)>` to
+support per-configuration specification.  For example, the code:
+
+.. code-block:: cmake
+
+  set(CMAKE_MSVC_DEBUG_INFORMATION_FORMAT "$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>")
+
+selects for all following targets the program database debug information format
+for the Debug configuration.
+
+If this variable is not set, the :prop_tgt:`MSVC_DEBUG_INFORMATION_FORMAT`
+target property will not be set automatically.  If that property is not set,
+CMake selects a debug information format using the default value
+``$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>``, if supported by the
+compiler, and otherwise ``$<$<CONFIG:Debug,RelWithDebInfo>:Embedded>``.
+
+.. note::
+
+  This variable has effect only when policy :policy:`CMP0141` is set to ``NEW``
+  prior to the first :command:`project` or :command:`enable_language` command
+  that enables a language using a compiler targeting the MSVC ABI.
