Honor language standard in :command:`try_compile` source-file signature.
|
||
|
|
|
||
|
|
The :command:`try_compile` source file signature is intended to allow
|
||
|
|
callers to check whether they will be able to compile a given source file
|
||
|
|
with the current toolchain. In order to match compiler behavior, any
|
||
|
|
language standard mode should match. However, CMake 3.7 and below did not
|
||
|
|
do this. CMake 3.8 and above prefer to honor the language standard settings
|
||
|
|
for ``C``, ``CXX`` (C++), and ``CUDA`` using the values of the variables:
|
||
|
|
|
||
|
|
* :variable:`CMAKE_C_STANDARD`
|
||
|
|
* :variable:`CMAKE_C_STANDARD_REQUIRED`
|
||
|
|
* :variable:`CMAKE_C_EXTENSIONS`
|
||
|
|
* :variable:`CMAKE_CXX_STANDARD`
|
||
|
|
* :variable:`CMAKE_CXX_STANDARD_REQUIRED`
|
||
|
|
* :variable:`CMAKE_CXX_EXTENSIONS`
|
||
|
|
* :variable:`CMAKE_CUDA_STANDARD`
|
||
|
|
* :variable:`CMAKE_CUDA_STANDARD_REQUIRED`
|
||
|
|
* :variable:`CMAKE_CUDA_EXTENSIONS`
|
||
|
|
|
||
|
|
This policy provides compatibility for projects that do not expect
|
||
|
|
the language standard settings to be used automatically.
|
||
|
|
|
||
|
|
The ``OLD`` behavior of this policy is to ignore language standard
|
||
|
|
setting variables when generating the ``try_compile`` test project.
|
||
|
|
The ``NEW`` behavior of this policy is to honor language standard
|
||
|
|
setting variables.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.8. Unlike most policies,
|
||
|
|
CMake version |release| does *not* warn by default when this policy
|
||
|
|
is not set and simply uses ``OLD`` behavior. See documentation of the
|
||
|
|
:variable:`CMAKE_POLICY_WARNING_CMP0067 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
|
||
|
|
variable to control the warning.
