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.
