CMAKE_MSVC_RUNTIME_CHECKS
-------------------------
.. versionadded:: 4.0
Select the list of enabled runtime checks when targeting the MSVC ABI.
This variable is used to initialize the
:prop_tgt:`MSVC_RUNTIME_CHECKS` 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/include/MSVC_RUNTIME_CHECKS-VALUES.rst
Use :manual:`generator expressions <cmake-generator-expressions(7)>` to
support per-configuration specification. For example, the code:
.. code-block:: cmake
set(CMAKE_MSVC_RUNTIME_CHECKS "$<$<CONFIG:Debug,RelWithDebInfo>:PossibleDataLoss;UninitializedVariable>")
enables for the target ``foo`` the possible data loss and uninitialized variables checks
for the ``Debug`` and ``RelWithDebInfo`` configurations.
If this variable is not set, the :prop_tgt:`MSVC_RUNTIME_CHECKS`
target property will not be set automatically. If that property is not set,
CMake selects runtime checks using the default value
``$<$<CONFIG:Debug>:StackFrameErrorCheck;UninitializedVariable>``,
if supported by the compiler, or empty value otherwise.
.. note::
This variable has effect only when policy :policy:`CMP0184` 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.
